Strong +1: Shared extensions across profiles are a game-changer for power users!
When a new profile is created, it didn't carry over any extensions or add-ons—total setup nightmare from scratch every time.
This kills productivity for multi-profile users like me who rely on Firefox at home and work. Please prioritize an option to enable shared extensions/add-ons across profiles (with toggle per profile for flexibility). It's a simple profile-sync feature that would make Firefox unbeatable.
Thanks for considering—let's make profiles truly seamless!
