Known problems

• Startup hang with Firefox running in a container (e.g. snap, flatpak):

When Firefox is packaged inside a container (like the default Firefox browser shipped with Ubuntu 22.04), it may see a different filesystem to the host. This can affect access to the generated profile directory, which may result in a hang when starting Firefox. Workarounds are listed in the geckodriver usage documentation.

• Potential hang with moz:debuggerAddress capability set to true:

After enabling the site-isolation feature in Firefox with geckodriver 0.32.1 some WebDriver clients like Selenium that use the Chrome DevTools Protocol (CDP) by default for logging events could trigger a hang in Firefox's experimental CDP implementation. The fix for this problem will be shipped with Firefox 112. Until then the following Firefox preferences should be set:

• fission.bfcacheInParent: false
• fission.webContentIsolationStrategy: 0

Added

• Support for Get Computed Label and Get Computed Role

The command Get Computed Label returns the accessibility label (sometimes also referred to as Accessible Name), which is a short string that labels the function of the control (e.g. the string "Comment" or "Sign In" on a button).

The command Get Computed Role returns the reserved token value (in ARIA, button, heading, etc.) that describes the type of control or content in the element.

Note that the minimum required Firefox version is 113.0.

• Support for Find Element From Shadow Root and Find Elements From Shadow Root

The commands allow a lookup of individual elements or collections of elements within an open or closed Shadow DOM. All location strategies except Tag name and XPath selector are currently supported.

Note that the minimum required Firefox version is 113.0.

Changed

• The Mozilla specific capability moz:useNonSpecCompliantPointerOrigin has been marked as deprecated. Its removal is planned for the Firefox 116.0 release.
