Details

Found in

  • Firefox Enterprise 147.0a1 (Build ID: 20251205074303)

Affected versions

  • Firefox Enterprise 147.0a1

Tested platforms

  • Affected platforms: Windows 11 x64, Ubuntu 24.04 and macOS 26

Preconditions

  • Firefox Enterprise is launched and SSO authentication has completed successfully.

Steps to reproduce

  1. Change the OS theme.
  2. Observe the theme applied in Firefox Enterprise.

Expected result

  • Firefox Enterprise should update its theme automatically to match the OS theme.

Actual result

  • The Firefox Enterprise theme does not change when the OS theme changes.
  • There is no “System Theme” option available in Firefox Enterprise, so the browser remains unchanged while the OS theme switches.
  • This can be confusing for users who expect the browser to follow the OS theme.

Regression range

  • This is not a regression.
