0.37.1 (2026-07-20, 125896b8db38)

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 versions since 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].

Changed

• Browser UI testing for Firefox now requires the geckodriver
  [--allow-system-access] command-line argument. Setting the
  Firefox --remote-allow-system-access command-line argument
  via moz:firefoxOptions is no longer supported.

Fixed

• Fixed a regression in geckodriver 0.37.0 that could cause Firefox for Android
  to exit immediately on startup on non-rooted Android devices.
