DESCRIPTION

This is a client module to automate the Mozilla Firefox browser via the Marionette protocol

SUBROUTINES/METHODS

accept_alert

accepts a currently displayed modal message box

accept_connections

Enables or disables accepting new socket connections. By calling this method with false the server will not accept any further connections, but existing connections will not be forcible closed. Use true to re-enable accepting connections.

Please note that when closing the connection via the client you can end-up in a non-recoverable state if it hasn't been enabled before.

active_element

returns the active element of the current browsing context's document element, if the document element is non-null.

add_certificate

accepts a hash as a parameter and adds the specified certificate to the Firefox database with the supplied or default trust. Allowed keys are below;

path - a file system path to a single PEM encoded X.509 certificate.
string - a string containg a single PEM encoded X.509 certificate
trust - This is the trustargs value for NSS. If defaults to 'C,,';

use Firefox::Marionette();

my $pem_encoded_string = <<'_PEM_';
-----BEGIN CERTIFICATE-----
MII..
-----END CERTIFICATE-----
_PEM_
my $firefox = Firefox::Marionette->new()->add_certificate(string => $pem_encoded_string);

This method returns itself to aid in chaining methods.

add_cookie

accepts a single cookie object as the first parameter and adds it to the current cookie jar. This method returns itself to aid in chaining methods.

This method throws an exception if you try to add a cookie for a different domain than the current document.

add_header

accepts a hash of HTTP headers to include in every future HTTP Request.

use Firefox::Marionette();
use UUID();

my $firefox = Firefox::Marionette->new();
my $uuid = UUID::uuid();
$firefox->add_header( 'Track-my-automated-tests' => $uuid );
$firefox->go('https://metacpan.org/');

these headers are added to any existing headers. To clear headers, see the delete_header method

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new()->delete_header( 'Accept' )->add_header( 'Accept' => 'text/perl' )->go('https://metacpan.org/');

will only send out an Accept header that looks like Accept: text/perl.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new()->add_header( 'Accept' => 'text/perl' )->go('https://metacpan.org/');

by itself, will send out an Accept header that may resemble Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8, text/perl. This method returns itself to aid in chaining methods.

add_login

accepts a hash of the following keys;

host - The origin, not hostname, to which the login applies, for example 'https://www.example.org'.
user - The username for the login.
password - The password for the login.
origin - The origin, not URL, a form-based login was submitted to. For logins obtained from HTML forms, this field is the action attribute from the form element, with the path removed (for example, "https://example.org"). Forms with no action attribute default to submitting to their origin URL, so that is stored here. This field should be omitted (it will be set to undef) for http auth type authentications and "" means to match against any form action.
realm - The HTTP Realm for which the login was requested. When an HTTP server sends a 401 result, the WWW-Authenticate header includes a realm. See RFC 2617. If the realm is not specified, or it was blank, the hostname is used instead. For HTML form logins, this field is null.
user_field - The name attribute for the username input in a form. Non-form logins should specify an empty string (""), which it will default to if not specified.
password_field - The name attribute for the password input in a form. Non-form logins should specify an empty string (""), which it will default to if not specified.

or a Firefox::Marionette::Login object as the first parameter and adds the login to the Firefox login database.

use Firefox::Marionette();
use UUID();

my $firefox = Firefox::Marionette->new();

# for http auth logins

my $http_auth_login = Firefox::Marionette::Login->new(host => 'https://pause.perl.org', user => 'AUSER', password => 'qwerty', realm => 'PAUSE');
$firefox->add_login($http_auth_login);
$firefox->go('https://pause.perl.org/pause/authenquery')->accept_alert(); # this goes to the page and submits the http auth popup

# for form based login

$firefox->add_login(host => 'https://github.com', origin => 'https://github.com', user => 'me@example.org', password => 'qwerty', user_field => 'login', password_field => 'password');
my $form_login = Firefox::Marionette::Login(host => 'https://github.com', user => 'me2@example.org', password => 'uiop[]', user_field => 'login', password_field => 'password');

# or just directly

$firefox->add_login(host => 'https://github.com/login', user => 'me2@example.org', password => 'uiop[]', user_field => 'login', password_field => 'password');

This method returns itself to aid in chaining methods.

add_site_header

accepts a host name and a hash of HTTP headers to include in every future HTTP Request that is being sent to that particular host.

use Firefox::Marionette();
use UUID();

my $firefox = Firefox::Marionette->new();
my $uuid = UUID::uuid();
$firefox->add_site_header( 'metacpan.org', 'Track-my-automated-tests' => $uuid );
$firefox->go('https://metacpan.org/');

these headers are added to any existing headers going to the metacpan.org site, but no other site. To clear site headers, see the delete_site_header method

addons

returns if pre-existing addons (extensions/themes) are allowed to run. This will be true for Firefox versions less than 55, as -safe-mode cannot be automated.

alert_text

Returns the message shown in a currently displayed modal message box

alive

This method returns true or false depending on if the Firefox process is still running.

application_type

returns the application type for the Marionette protocol. Should be 'gecko'.

async_script

accepts a scalar containing a javascript function that is executed in the browser. This method returns itself to aid in chaining methods.

The executing javascript is subject to the script timeout, which, by default is 30 seconds.

attribute

accepts an element as the first parameter and a scalar attribute name as the second parameter. It returns the initial value of the attribute with the supplied name. This method will return the initial content, the property method will return the current content.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/');
my $element = $firefox->find_id('search_input');
!defined $element->attribute('value') or die "attribute is not defined!");
$element->type('Test::More');
!defined $element->attribute('value') or die "attribute is still not defined!");

await

accepts a subroutine reference as a parameter and then executes the subroutine. If a not found exception is thrown, this method will sleep for sleep_time_in_ms milliseconds and then execute the subroutine again. When the subroutine executes successfully, it will return what the subroutine returns.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new(sleep_time_in_ms => 5)->go('https://metacpan.org/');

$firefox->find_id('search-input')->type('Test::More');

$firefox->find_name('lucky')->click();

$firefox->await(sub { $firefox->interactive() && $firefox->find_partial('Download') })->click();

back

causes the browser to traverse one step backward in the joint history of the current browsing context. The browser will wait for the one step backward to complete or the session's page_load duration to elapse before returning, which, by default is 5 minutes. This method returns itself to aid in chaining methods.

browser_version

This method returns the current version of firefox.

bye

accepts a subroutine reference as a parameter and then executes the subroutine. If the subroutine executes successfully, this method will sleep for sleep_time_in_ms milliseconds and then execute the subroutine again. When a not found exception is thrown, this method will return itself to aid in chaining methods.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/');

$firefox->find_id('search-input')->type('Test::More');

$firefox->find_name('lucky')->click();

$firefox->bye(sub { $firefox->find_name('lucky') })->await(sub { $firefox->interactive() && $firefox->find_partial('Download') })->click();

capabilities

returns the capabilities of the current firefox binary. You can retrieve timeouts or a proxy with this method.

certificate_as_pem

accepts a certificate stored in the Firefox database as a parameter and returns a PEM encoded X.509 certificate as a string.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new();

# Generating a ca-bundle.crt to STDOUT from the current firefox instance

foreach my $certificate (sort { $a->display_name() cmp $b->display_name } $firefox->certificates()) {
    if ($certificate->is_ca_cert()) {
        print '# ' . $certificate->display_name() . "\n" . $firefox->certificate_as_pem($certificate) . "\n";
    }
}

The ca-bundle-for-firefox command that is provided as part of this distribution does this.

certificates

returns a list of all known certificates in the Firefox database.

use Firefox::Marionette();
use v5.10;

# Sometimes firefox can neglect old certificates.  See https://bugzilla.mozilla.org/show_bug.cgi?id=1710716

my $firefox = Firefox::Marionette->new();
foreach my $certificate (grep { $_->is_ca_cert() && $_->not_valid_after() < time } $firefox->certificates()) {
    say "The " . $certificate->display_name() " . certificate has expired and should be removed";
}

This method returns itself to aid in chaining methods.

child_error

This method returns the $? (CHILD_ERROR) for the Firefox process, or undefined if the process has not yet exited.

chrome

changes the scope of subsequent commands to chrome context. This allows things like interacting with firefox menu's and buttons outside of the browser window.

use Firefox::Marionette();
use v5.10;

my $firefox = Firefox::Marionette->new()->chrome();
$firefox->script(...); # running script in chrome context
$firefox->content();

See the context method for an alternative methods for changing the context.

chrome_window_handle

returns an server-assigned integer identifiers for the current chrome window that uniquely identifies it within this Marionette instance. This can be used to switch to this window at a later point. This corresponds to a window that may itself contain tabs.

chrome_window_handles

returns identifiers for each open chrome window for tests interested in managing a set of chrome windows and tabs separately.

clear

accepts a element as the first parameter and clears any user supplied input

click

accepts a element as the first parameter and sends a 'click' to it. The browser will wait for any page load to complete or the session's page_load duration to elapse before returning, which, by default is 5 minutes. The click method is also used to choose an option in a select dropdown.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new(visible => 1)->go('https://ebay.com');
my $select = $firefox->find_tag('select');
foreach my $option ($select->find_tag('option')) {
    if ($option->property('value') == 58058) { # Computers/Tablets & Networking
        $option->click();
    }
}

close_current_chrome_window_handle

closes the current chrome window (that is the entire window, not just the tabs). It returns a list of still available chrome window handles. You will need to switch_to_window to use another window.

close_current_window_handle

closes the current window/tab. It returns a list of still available window/tab handles.

content

changes the scope of subsequent commands to browsing context. This is the default for when firefox starts and restricts commands to operating in the browser window only.

use Firefox::Marionette();
use v5.10;

my $firefox = Firefox::Marionette->new()->chrome();
$firefox->script(...); # running script in chrome context
$firefox->content();

See the context method for an alternative methods for changing the context.

context

accepts a string as the first parameter, which may be either 'content' or 'chrome'. It returns the context type that is Marionette's current target for browsing context scoped commands.

use Firefox::Marionette();
use v5.10;

my $firefox = Firefox::Marionette->new();
if ($firefox->context() eq 'content') {
   say "I knew that was going to happen";
}
my $old_context = $firefox->context('chrome');
$firefox->script(...); # running script in chrome context
$firefox->context($old_context);

See the content and chrome methods for alternative methods for changing the context.

cookies

returns the contents of the cookie jar in scalar or list context.

    if (defined $cookie->same_site()) {
        say "Cookie " . $cookie->name() . " has a SameSite of " . $cookie->same_site();
    } else {
        warn "Cookie " . $cookie->name() . " does not have the SameSite attribute defined";
    }
}

css

accepts an element as the first parameter and a scalar CSS property name as the second parameter. It returns the value of the computed style for that property.

use Firefox::Marionette();
use v5.10;

my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/');
say $firefox->find_id('search-input')->css('height');

current_chrome_window_handle

see chrome_window_handle.

delete_certificate

accepts a certificate stored in the Firefox database as a parameter and deletes/distrusts the certificate from the Firefox database.

use Firefox::Marionette();
use v5.10;

my $firefox = Firefox::Marionette->new();
foreach my $certificate ($firefox->certificates()) {
    if ($certificate->is_ca_cert()) {
        $firefox->delete_certificate($certificate);
    } else {
        say "This " . $certificate->display_name() " certificate is NOT a certificate authority, therefore it is not being deleted";
    }
}
say "Good luck visiting a HTTPS website!";

This method returns itself to aid in chaining methods.

delete_cookie

deletes a single cookie by name. Accepts a scalar containing the cookie name as a parameter. This method returns itself to aid in chaining methods.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new()->go('https://github.com');

    warn "Cookie " . $cookie->name() . " is being deleted";
    $firefox->delete_cookie($cookie->name());
}
foreach my $cookie ($firefox->cookies()) {
    die "Should be no cookies here now";
}

delete_cookies

here be cookie monsters! This method returns itself to aid in chaining methods.

delete_header

accepts a list of HTTP header names to delete from future HTTP Requests.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new();
$firefox->delete_header( 'User-Agent', 'Accept', 'Accept-Encoding' );

will remove the User-Agent, Accept and Accept-Encoding headers from all future requests

This method returns itself to aid in chaining methods.

delete_login

accepts a login as a parameter.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new();
foreach my $login ($firefox->logins()) {
    if ($login->user() eq 'me@example.org') {

developer

returns true if the current version of firefox is a developer edition (does the minor version number end with an 'b\d+'?) version.

dismiss_alert

dismisses a currently displayed modal message box

download

accepts a filesystem path and returns a matching filehandle. This is trivial for locally running firefox, but sufficiently complex to justify the method for a remote firefox running over ssh.

Navigates the current browsing context to the given URI and waits for the document to load or the session's page_load duration to elapse before returning, which, by default is 5 minutes.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new();
$firefox->go('https://metacpan.org/'); # will only return when metacpan.org is FULLY loaded (including all images / js / css)

To make the go method return quicker, you need to set the page load strategy capability to an appropriate value, such as below;

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new( capabilities => Firefox::Marionette::Capabilities->new( page_load_strategy => 'eager' ));
$firefox->go('https://metacpan.org/'); # will return once the main document has been loaded and parsed, but BEFORE sub-resources (images/stylesheets/frames) have been loaded.

This method returns itself to aid in chaining methods.

har

returns a hashref representing the http archive of the session. This function is subject to the script timeout, which, by default is 30 seconds. It is also possible for the function to hang (until the script timeout) if the original devtools window is closed. The hashref has been designed to be accepted by the Archive::Har module. This function should be considered experimental. Feedback welcome.

use Firefox::Marionette();
use Archive::Har();
use v5.10;

my $firefox = Firefox::Marionette->new(visible => 1, debug => 1, har => 1);

$firefox->go("http://metacpan.org/");

use v5.10;

say Firefox::Marionette->new()->go('https://metacpan.org/')->html();

install

accepts the following as the first parameter;

path to an xpi file.
path to a directory containing firefox extension source code. This directory will be packaged up as an unsigned xpi file.
path to a top level file (such as manifest.json) in a directory containing firefox extension source code. This directory will be packaged up as an unsigned xpi file.

and an optional true/false second parameter to indicate if the xpi file should be a temporary extension (just for the existance of this browser instance). Unsigned xpi files may only be loaded temporarily (except for nightly firefox installations). It returns the GUID for the addon which may be used as a parameter to the uninstall method.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new();

my $extension_id = $firefox->install('/full/path/to/gnu_terry_pratchett-0.4-an+fx.xpi');

marionette_protocol

returns the version for the Marionette protocol. Current most recent version is '3'.

maximise

maximises the firefox window. This method returns itself to aid in chaining methods.

mime_types

}

minimise

minimises the firefox window. This method returns itself to aid in chaining methods.

mouse_move

accepts a element parameter, or a ( x => 0, y => 0 ) type hash manually describing exactly where to move the mouse to and returns an action for use in the perform method that corresponding with such a mouse movement, either to the specified co-ordinates or to the middle of the supplied element parameter.

mouse_up

new

accepts an optional hash as a parameter. Allowed keys are below;

addons - should any firefox extensions and themes be available in this session. This defaults to "0".
capabilities - use the supplied capabilities object, for example to set whether the browser should accept insecure certs or whether the browser should use a proxy.
chatty - Firefox is extremely chatty on the network, including checking for the lastest malware/phishing sites, updates to firefox/etc. This option is therefore off ("0") by default, however, it can be switched on ("1") if required. Even with chatty switched off, connections to firefox.settings.services.mozilla.com will still be made. The only way to prevent this seems to be to set firefox.settings.services.mozilla.com to 127.0.0.1 via /etc/hosts. NOTE: that this option only works when profile_name/profile is not specified.
console - show the browser console when the browser is launched. This defaults to "0" (off).
debug - should firefox's debug to be available via STDERR. This defaults to "0". Any ssh connections will also be printed to STDERR. This defaults to "0" (off).
developer - only allow a developer edition to be launched. This defaults to "0" (off).
firefox - use the specified path to the Firefox binary, rather than the default path.
height - set the height of the initial firefox window
har - begin the session with the devtools window opened in a separate window. The HAR Export Trigger addon will be loaded into the new session automatically, which means that -safe-mode will not be activated for this session AND this functionality will only be available for Firefox 61+.
host - use ssh to create and automate firefox on the specified host. See REMOTE AUTOMATION OF FIREFOX VIA SSH.
implicit - a shortcut to allow directly providing the implicit timeout, instead of needing to use timeouts from the capabilities parameter. Overrides all longer ways.
mime_types - any MIME types that Firefox will encounter during this session. MIME types that are not specified will result in a hung browser (the File Download popup will appear).
nightly - only allow a nightly release to be launched. This defaults to "0" (off).
port - if the "host" parameter is also set, use ssh to create and automate firefox via the specified port. See REMOTE AUTOMATION OF FIREFOX VIA SSH.
page_load - a shortcut to allow directly providing the page_load timeout, instead of needing to use timeouts from the capabilities parameter. Overrides all longer ways.
profile - create a new profile based on the supplied profile. NOTE: firefox ignores any changes made to the profile on the disk while it is running.
profile_name - pick a specific existing profile to automate, rather than creating a new profile. Firefox refuses to allow more than one instance of a profile to run at the same time. Profile names can be obtained by using the Firefox::Marionette::Profile::names() method. NOTE: firefox ignores any changes made to the profile on the disk while it is running.
reconnect - an experimental parameter to allow a reconnection to firefox that a connection has been discontinued. See the survive parameter.
script - a shortcut to allow directly providing the script timeout, instead of needing to use timeouts from the capabilities parameter. Overrides all longer ways.
seer - this option is switched off "0" by default. When it is switched on "1", it will activate the various speculative and pre-fetch options for firefox. NOTE: that this option only works when profile_name/profile is not specified.
sleep_time_in_ms - the amount of time (in milliseconds) that this module should sleep when unsuccessfully calling the subroutine provided to the await or bye methods. This defaults to "1" millisecond.
survive - if this is set to a true value, firefox will not automatically exit when the object goes out of scope. See the reconnect parameter for an experimental technique for reconnecting.
trust - give a path to a root certificate encoded as a PEM encoded X.509 certificate that will be trusted for this session.
timeouts - a shortcut to allow directly providing a timeout object, instead of needing to use timeouts from the capabilities parameter. Overrides the timeouts provided (if any) in the capabilities parameter.
user - if the "host" parameter is also set, use ssh to create and automate firefox with the specified user. See REMOTE AUTOMATION OF FIREFOX VIA SSH. The user will default to the current user name.
visible - should firefox be visible on the desktop. This defaults to "0".
waterfox - only allow a binary that looks like a waterfox version to be launched.
width - set the width of the initial firefox window

This method returns a new Firefox::Marionette object, connected to an instance of firefox. In a non MacOS/Win32/Cygwin environment, if necessary (no DISPLAY variable can be found and the visible parameter to the new method has been set to true) and possible (Xvfb can be executed successfully), this method will also automatically start an Xvfb instance.

use Firefox::Marionette();

my $remote_darwin_firefox = Firefox::Marionette->new(
                 debug => 1,
                 host => '10.1.2.3',
                 trust => '/path/to/root_ca.pem',
                 firefox => '/Applications/Firefox.app/Contents/MacOS/firefox'
                                                    ); # start a temporary profile for a remote firefox and load a new CA into the temp profile
...

foreach my $profile_name (Firefox::Marionette::Profile->names()) {
    my $firefox_with_existing_profile = Firefox::Marionette->new( profile_name => $profile_name, visible => 1 );
    ...
}

new_window

accepts an optional hash as the parameter. Allowed keys are below;

focus - a boolean field representing if the new window be opened in the foreground (focused) or background (not focused). Defaults to false.
private - a boolean field representing if the new window should be a private window. Defaults to false.
type - the type of the new window. Can be one of 'tab' or 'window'. Defaults to 'tab'.

Returns the window handle for the new window.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new();

my $window_handle = $firefox->new_window(type => 'tab');

$firefox->switch_to_window($window_handle);

new_session

creates a new WebDriver session. It is expected that the caller performs the necessary checks on the requested capabilities to be WebDriver conforming. The WebDriver service offered by Marionette does not match or negotiate capabilities beyond type and bounds checks.

nightly

returns true if the current version of firefox is a nightly release (does the minor version number end with an 'a1'?)

paper_sizes

returns a list of all the recognised names for paper sizes, such as A4 or LEGAL.

pause

accepts a parameter in milliseconds and returns a corresponding action for the perform method that will cause a pause in the chain of actions given to the perform method.

pdf

returns a File::Temp object containing a PDF encoded version of the current page for printing.

accepts a optional hash as the first parameter with the following allowed keys;

landscape - Paper orientation. Boolean value. Defaults to false
margin - A hash describing the margins. The hash may have the following optional keys, 'top', 'left', 'right' and 'bottom'. All these keys are in cm and default to 1 (~0.4 inches)
page - A hash describing the page. The hash may have the following keys; 'height' and 'width'. Both keys are in cm and default to US letter size. See the 'size' key.
print_background - Print background graphics. Boolean value. Defaults to false.
raw - rather than a file handle containing the PDF, the binary PDF will be returned.
scale - Scale of the webpage rendering. Defaults to 1.
size - The desired size (width and height) of the pdf, specified by name. See the page key for an alternative and the paper_sizes method for a list of accepted page size names.
shrink_to_fit - Whether or not to override page size as defined by CSS. Boolean value. Defaults to true.

    use Firefox::Marionette();

    my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/');
    my $handle = $firefox->pdf();
    foreach my $paper_size ($firefox->paper_sizes()) {
	    $handle = $firefox->pdf(size => $paper_size, landscape => 1, margin => { top => 0.5, left => 1.5 });
            ...
	    print $firefox->pdf(page => { width => 21, height => 27 }, raw => 1);
            ...
    }

perform

accepts a list of actions (see mouse_up, mouse_down, mouse_move, pause, key_down and key_up) and performs these actions in sequence. This allows fine control over interactions, including sending right clicks to the browser and sending Control, Alt and other special keys. The release method will complete outstanding actions (such as mouse_up or key_up actions).

    use Firefox::Marionette();
    use Firefox::Marionette::Keys qw(:all);
    use Firefox::Marionette::Buttons qw(:all);

    my $firefox = Firefox::Marionette->new();

    $firefox->chrome()->perform(
                                 $firefox->key_down(CONTROL()),
                                 $firefox->key_down('l'),
                                 $firefox->key_up('l'),
                                 $firefox->key_up(CONTROL())
                               )->content();

    $firefox->go('https://metacpan.org');
    my $help_button = $firefox->find_class('btn search-btn help-btn');
    $firefox->perform(
			          $firefox->mouse_move($help_button),
			          $firefox->mouse_down(RIGHT_BUTTON()),
			          $firefox->pause(4),
			          $firefox->mouse_up(RIGHT_BUTTON()),
		);

See the release method for an alternative for manually specifying all the mouse_up and key_up methods

profile_directory

refresh

refreshes the current page. The browser will wait for the page to completely refresh or the session's page_load duration to elapse before returning, which, by default is 5 minutes. This method returns itself to aid in chaining methods.

release

completes any outstanding actions issued by the perform method.

    use Firefox::Marionette();

sandbox - Name of the sandbox to evaluate the script in. The sandbox is cached for later re-use on the same window object if new is false. If he parameter is undefined, the script is evaluated in a mutable sandbox. If the parameter is "system", it will be evaluted in a sandbox with elevated system privileges, equivalent to chrome space.
timeout - A timeout to override the default script timeout, which, by default is 30 seconds.

Returns the result of the javascript function.

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new()->go('https://metacpan.org/');

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new(sleep_time_in_ms => 5); # setting default time to 5 milliseconds

my $old_time_in_ms = $firefox->sleep_time_in_ms(8); # setting default time to 8 milliseconds, returning 5 (milliseconds)

strip

returns the page source of the content document after an attempt has been made to remove typical firefox html wrappers of non html content types such as text/plain and application/json. See the json method for an alternative when dealing with response content types such as application/json and html for an alterative when dealing with html content types. This is a convenience method that wraps the html method.

use Firefox::Marionette();
use JSON();
use v5.10;

say JSON::decode_json(Firefox::Marionette->new()->go("https://fastapi.metacpan.org/v1/download_url/Firefox::Marionette")->strip())->{version};

# do something

$firefox->uninstall($extension_id); # not recommended to uninstall this extension IRL.

uri

returns the current URI of current top level browsing context for Desktop. It is equivalent to the javascript document.location.href

window_handle

returns the current window's handle. On desktop this typically corresponds to the currently selected tab. returns an opaque server-assigned identifier to this window that uniquely identifies it within this Marionette instance. This can be used to switch to this window at a later point.

window_handles

returns a list of top-level browsing contexts. On desktop this typically corresponds to the set of open tabs for browser windows, or the window itself for non-browser chrome windows. Each window handle is assigned by the server and is guaranteed unique, however the return array does not have a specified ordering.

window_rect

AUTOMATING THE FIREFOX PASSWORD MANAGER

This module allows you to login to a website without ever directly handling usernames and password details. The Password Manager may be preloaded with appropriate passwords and locked, like so;

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new( profile_name => 'locked' ); # using a pre-built profile called 'locked'
if ($firefox->pwd_mgr_needs_login()) {
    my $new_password = IO::Prompt::prompt(-echo => q[*], 'Enter the password for the locked profile:');
    $firefox->pwd_mgr_login($password);
} else {
    my $new_password = IO::Prompt::prompt(-echo => q[*], 'Enter the new password for the locked profile:');
    $firefox->pwd_mgr_lock($password);
}
...
$firefox->pwd_mgr_logout();

Usernames and passwords (for both HTTP Authentication popups and HTML Form based logins) may be added, viewed and deleted.

use WebService::HIBP();

my $hibp = WebService::HIBP->new();

$firefox->add_login(host => 'https://github.com', user => 'me@example.org', password => 'qwerty', user_field => 'login', password_field => 'password');
$firefox->add_login(host => 'https://pause.perl.org', user => 'AUSER', password => 'qwerty', realm => 'PAUSE');
...

REMOTE AUTOMATION OF FIREFOX VIA SSH

use Firefox::Marionette();

my $firefox = Firefox::Marionette->new( host => 'remote.example.org', debug => 1 );
$firefox->go('https://metacpan.org/');

# OR specify a different user to login as ...

my $firefox = Firefox::Marionette->new( host => 'remote.example.org', user => 'R2D2', debug => 1 );
$firefox->go('https://metacpan.org/');

# OR specify a different port to connect to

my $firefox = Firefox::Marionette->new( host => 'remote.example.org', port => 2222, debug => 1 );
$firefox->go('https://metacpan.org/');

This module has support for creating and automating an instance of Firefox on a remote node. It has been tested against a number of operating systems, including recent version of Windows 10 or Windows Server 2019, OS X, and Linux and BSD distributions. It expects to be able to login to the remote node via public key authentication. It can be further secured via the command option in the OpenSSH authorized_keys file such as;

no-agent-forwarding,no-pty,no-X11-forwarding,permitopen="127.0.0.1:*",command="/usr/local/bin/ssh-auth-cmd-marionette" ssh-rsa AAAA ... == user@server

As an example, the ssh-auth-cmd-marionette command is provided as part of this distribution.

When using ssh, Firefox::Marionette will attempt to pass the TMPDIR environment variable across the ssh connection to make cleanups easier. In order to allow this, the AcceptEnv setting in the remote sshd configuration should be set to allow TMPDIR, which will look like;

AcceptEnv TMPDIR

This module uses ControlMaster functionality when using ssh, for a useful speedup of executing remote commands. Unfortunately, when using ssh to move from a cygwin, Windows 10 or Windows Server 2019 node to a remote environment, we cannot use ControlMaster, because at this time, Windows does not support ControlMaster and therefore this type of automation is still possible, but slower than other client platforms.

DIAGNOSTICS

Failed to correctly setup the Firefox process: The module was unable to retrieve a session id and capabilities from Firefox when it requests a new_session as part of the initial setup of the connection to Firefox.
Failed to correctly determined the Firefox process id through the initial connection capabilities: The module was found that firefox is reporting through it's Capabilities object a different process id than this module was using. This is probably a bug in this module's logic. Please report as described in the BUGS AND LIMITATIONS section below.
'%s --version' did not produce output that could be parsed. Assuming modern Marionette is available:%s: The Firefox binary did not produce a version number that could be recognised as a Firefox version number.
Failed to create process from '%s':%s: The module was to start Firefox process in a Win32 environment. Something is seriously wrong with your environment.
Failed to redirect %s to %s:%s: The module was unable to redirect a file handle's output. Something is seriously wrong with your environment.
Failed to exec %s:%s: The module was unable to run the Firefox binary. Check the path is correct and the current user has execute permissions.
Failed to fork:%s: The module was unable to fork itself, prior to executing a command. Check the current ulimit for max number of user processes.
Failed to open directory '%s':%s: The module was unable to open a directory. Something is seriously wrong with your environment.
Failed to close directory '%s':%s: The module was unable to close a directory. Something is seriously wrong with your environment.
Failed to open '%s' for writing:%s: The module was unable to create a file in your temporary directory. Maybe your disk is full?
Failed to open temporary file for writing:%s: The module was unable to create a file in your temporary directory. Maybe your disk is full?
Failed to close '%s':%s: The module was unable to close a file in your temporary directory. Maybe your disk is full?
Failed to close temporary file:%s: The module was unable to close a file in your temporary directory. Maybe your disk is full?
Failed to create temporary directory:%s: The module was unable to create a directory in your temporary directory. Maybe your disk is full?
Failed to clear the close-on-exec flag on a temporary file:%s: The module was unable to call fcntl using F_SETFD for a file in your temporary directory. Something is seriously wrong with your environment.
Failed to seek to start of temporary file:%s: The module was unable to seek to the start of a file in your temporary directory. Something is seriously wrong with your environment.
Failed to create a socket:%s: The module was unable to even create a socket. Something is seriously wrong with your environment.
Failed to connect to %s on port %d:%s: The module was unable to connect to the Marionette port. This is probably a bug in this module's logic. Please report as described in the BUGS AND LIMITATIONS section below.
Firefox killed by a %s signal (%d): Firefox crashed after being hit with a signal.
Firefox exited with a %d: Firefox has exited with an error code
Failed to bind socket:%s: The module was unable to bind a socket to any port. Something is seriously wrong with your environment.
Failed to close random socket:%s: The module was unable to close a socket without any reads or writes being performed on it. Something is seriously wrong with your environment.
moz:headless has not been determined correctly: The module was unable to correctly determine whether Firefox is running in "headless" or not. This is probably a bug in this module's logic. Please report as described in the BUGS AND LIMITATIONS section below.
%s method requires a Firefox::Marionette::Element parameter: This function was called incorrectly by your code. Please supply a Firefox::Marionette::Element parameter when calling this function.
Failed to write to temporary file:%s: The module was unable to write to a file in your temporary directory. Maybe your disk is full?
Failed to close socket to firefox:%s: The module was unable to even close a socket. Something is seriously wrong with your environment.
Failed to send request to firefox:%s: The module was unable to perform a syswrite on the socket connected to firefox. Maybe firefox crashed?
Failed to read size of response from socket to firefox:%s: The module was unable to read from the socket connected to firefox. Maybe firefox crashed?
Failed to read response from socket to firefox:%s: The module was unable to read from the socket connected to firefox. Maybe firefox crashed?
