They keep saying their ai features will be opt-in, and yet everything they've rolled out so far is opt-out. I struggle to believe future 'features' will be any different. Maybe it's opt-in in the sense that I'm not required to click whichever button activates it, like whatever they added to the context menu, but that's not really what opt-in means and degrades my trust in Mozilla.

I'm also frustrated by their seeming inability to focus on their core browser product and building a popular competitor to chromium browsers instead of going off on side quests.
