Firefox::Marionette::Capabilities - Represents Firefox Capabilities retrieved using the Marionette protocol

Version 1.35

    use Firefox::Marionette();
    use v5.10;
    my $firefox = Firefox::Marionette->new( capabilities => Firefox::Marionette::Capabilities->new( accept_insecure_certs => 0 ) );
    if ($firefox->capabilities->accept_insecure_certs()) {
        say "Browser will now ignore certificate failures";
    }

This module handles the implementation of Firefox Capabilities using the Marionette protocol

indicates whether untrusted and self-signed TLS certificates are implicitly trusted on navigation for the duration of the session.

returns the browsers name. For example 'firefox'

returns the version of firefox <https://firefox.com/>

This method returns a list of strings describing the capabilities that this version of Firefox supports.

returns the current accessibility (a11y) value

returns the Firefox BuildId <https://developer.mozilla.org/en-US/docs/Web/API/Navigator/buildID>

returns whether the browser is running in headless mode

returns the process id belonging to the browser

returns the directory that contains the browsers profile

returns the value of moz:shutdownTimeout <https://github.com/mozilla/gecko-dev/commit/7aad85995b21bdaf440dc9dad35c5769a35e90eb#diff-48053ba06cc33be0efb2d7256a1affd9> (aka the value of config toolkit.asyncshutdown.crash_timeout)

returns a boolean value to indicate how the pointer origin for an action command will be calculated.

With Firefox 59 the calculation will be based on the requirements by the WebDriver specification. This means that the pointer origin is no longer computed based on the top and left position of the referenced element, but on the in-view center point.

To temporarily disable the WebDriver conformant behavior use 0 as value for this capability.

Please note that this capability exists only temporarily, and that it will be removed once all Selenium bindings can handle the new behavior.

returns a boolean value to indicate which kind of interactability checks to run when performing a click or sending keys to an elements. For Firefoxen prior to version 58.0 some legacy code as imported from an older version of FirefoxDriver was in use.

With Firefox 58 the interactability checks as required by the WebDriver specification are enabled by default. This means geckodriver will additionally check if an element is obscured by another when clicking, and if an element is focusable for sending keys.

Because of this change in behaviour, we are aware that some extra errors could be returned. In most cases the test in question might have to be updated so it's conform with the new checks. But if the problem is located in geckodriver, then please raise an issue in the issue tracker.

To temporarily disable the WebDriver conformant checks use 0 as value for this capability.

Please note that this capability exists only temporarily, and that it will be removed once the interactability checks have been stabilized.

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

  • accept_insecure_certs - Indicates whether untrusted and self-signed TLS certificates are implicitly trusted on navigation for the duration of the session. Allowed values are 1 or 0. Default is 0.
  • moz_accessibility_checks - run a11y checks when clicking elements. Allowed values are 1 or 0. Default is 0.
  • moz_headless - the browser should be started with the -headless option. moz_headless is only supported in Firefox 56+
  • moz_use_non_spec_compliant_pointer_origin - a boolean value to indicate how the pointer origin for an action command will be calculated.

    With Firefox 59 the calculation will be based on the requirements by the WebDriver specification. This means that the pointer origin is no longer computed based on the top and left position of the referenced element, but on the in-view center point.

  • page_load_strategy - defines the page load strategy for the upcoming browser session.
  • proxy - describes the proxy setup for the upcoming browser session.
  • strict_file_interactability - a boolean value to indicate if interactability checks will be applied to <input type=file>. Allowed values are 1 or 0. Default is 0.
  • timeouts - describes the timeouts imposed on certain session operations.
  • unhandled_prompt_behavior - defines what firefox should do on encountering a user prompt <https://html.spec.whatwg.org/#user-prompts>. There are a range of allowed values <https://w3c.github.io/webdriver/#dfn-user-prompt-handler>, including "dismiss", "accept", "dismiss and notify", "accept and notify" and "ignore".

This method returns a new capabilities object.

returns the page load strategy <https://w3c.github.io/webdriver/#dfn-table-of-page-load-strategies> to use for the duration of the session. The page load strategy corresponds to the readyState <https://developer.mozilla.org/en-US/docs/Web/API/Document/readyState#Values> and may be one of the following values;

  • normal - Wait for the document and all sub-resources have finished loading. The corresponding readyState <https://developer.mozilla.org/en-US/docs/Web/API/Document/readyState#Values> is "complete". The load <https://developer.mozilla.org/en-US/docs/Web/Events/load> event is about to fire. This strategy is the default value.
  • eager - Wait for the document to have finished loading and have been parsed. Sub-resources such as images, stylesheets and frames are still loading. The corresponding readyState <https://developer.mozilla.org/en-US/docs/Web/API/Document/readyState#Values> is "interactive".
  • none - return immediately after starting navigation. The corresponding readyState <https://developer.mozilla.org/en-US/docs/Web/API/Document/readyState#Values> is "loading".

returns the operating system name. For example 'linux', 'darwin' or 'windows_nt'.

returns the current proxy object

returns the operation system version. For example '4.14.11-300.fc27.x86_64', '17.3.0' or '10.0'

does this version of firefox <https://firefox.com> have a rotatable screen such as Android Fennec.

returns true if Firefox fully supports setWindowRect <https://w3c.github.io/webdriver/#dfn-window-dimensioning-positioning>, otherwise it returns false.

returns the current value of strictFileInteractability <https://w3c.github.io/webdriver/#dfn-strict-file-interactability>

returns the current timeouts object

returns the current value of unhandledPromptBehavior <https://w3c.github.io/webdriver/#dfn-user-prompt-handler>.

None.

Firefox::Marionette::Capabilities requires no configuration files or environment variables.

None.

None reported.
