Yeah, this is the rub of it. I don’t want my browser to know about me. It’s not necessary. What are they gonna do, release a gaming-aesthetic browser like Opera did? Can’t this data be gleaned some most definitely not identifiable way like download number for particular platforms (“hey, we’re getting a lot of use on Steam Deck”) or something?
Mozilla is supposed to be better than this. I don’t really see anywhere else to go though if you want a web experience that works out of the box (non-free codecs and the like).
