I’m sorry, I’m not often someone to whine about Firefox UI. Usually their changes have been for good actually. BUT! But but but. Proper UI design would require AI features to be disabled if the toggle is disabled. This is both highly silly and very confusing.
Pushing the opt out responsibility on the user is why I left Windows and never looked back. I recommend Waterfox which I started using a couple months back when Firefox started going in this direction. Waterfox is great on desktop and Android (which I’ll hopefully shed soon too when my current phone stops working).
