Sooooooo annoying that Mozilla removed this feature. Would have been nice to mention this in the release notes so I wouldn't think I was going crazy wondering why my long-established searchbox workflow wasn't working anymore.Thanks anyway to jscher20...
extensions.unifiedExtensions.enabled set to False is NO LONGER a solution after v111.0 update! Why!? I guess I have to first update Firefox in a test environment since devs are so intent on sabotaging their users.
