Description

[Simona Badau, Desktop QA, PTO 22-30June]

Found in

• Nightly 134.0a1

Affected versions

• Nightly 134.0a1

Tested platforms

• Affected platforms: Windows 11 x64, macOS 15.

Preconditions

• Ensure that the pref "browser.profiles.enabled" is set to true in about:config.

Steps to reproduce

1. Click on Manage Profiles.
2. Check the Show this when Firefox opens box.
3. Quit all existing Firefox windows.
4. Open Firefox again.
5. Create a new profile in the Profile selector window.
6. Uncheck the Show this when Firefox opens box.
7. Open any of the profiles.
8. Switch to the profile created in step 5

Expected result

• The profile created in step 5 should have Profile Switching enabled and belong to the same profiles group as the original profile.

Actual result

• The new profile created in the Profile selector window does not have the toolkit.profiles.storeID preference set (hence, it is not linked to the other profiles), and the browser.profiles.enabled preference is not set to true.

Verified as fixed using the latest Nightly 136.0a1 (Build ID: 20250116214017) on macOS 15 and Windows 11. The profile created in the Profile Selector window now correctly belongs to the same profile group.
