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.
I think thats not what OP is mildly infuriated about though. If I understood correctly its that you have to enable the setting “disable AI” instead of having a setting “use AI” (possibly enabled by default), which you would disable. Its just counterintuitive semantics
