Found in

• Nightly 146.0a1

Affected versions

• Nightly 146.0a1

Tested platforms

• Affected platforms: Windows 11 x64

Preconditions

• Ensure at least one switchable profile exists - Profile A.
• A shortcut for Profile A is created via about:editprofile.
• A Nightly shortcut (that is not linked to any specific profile) is created.
• Ensure no Nightly icon is pinned to the Taskbar.

Steps to reproduce

1. Launch Profile A.
2. In the Taskbar - right click on Profile A, "Show more actions" and and select "Pin to Taskbar".
3. In the Taskbar - click on the Nightly icon that was just pinned.
4. Right click on the Firefox Nightly desktop shortcut, click on "Show more options" and select "Unpin from Taskbar".

Expected result

• In all the bellow steps - Nightly should behave in the same way as when Profile A is pinned from the context menu (right Click on Profile A icon -> Show more options and click Pin to Taskbar)
• In step 2 - Profile A should be pinned to the Taskbar.
• In step 3, Profile A should open.
• In step 4 - "Unpin from Taskbar" option should not be displayed for the generic Firefox Nightly shortcut, since Profile A was pinned.

Actual result

• In step 2 - Profile A is not truly pinned to the Taskbar.
• In step 3 - the Profile Selector opens instead of directly launching Profile A.
• In step 4 - the Nightly icon that was pinned from Profile A becomes unpinned from another Nightly desktop shortcut (from the generic one.)

Regression range

• not a regression.
