remember when firefox was all "customise your experience with extensions" before they conveniently forgot they could add all this AI bullshit as extensions?
any opt-out in the core browser doesn't matter if they're going to override your choices every upgrade.
literally the only useful ML-aided tool they've shipped is the local translations. okay, that one's proved itself, but why would i willingly waste the limited resources of my machine on stuff like tab grouping?
