It's interesting to notice how much my internal feelings have shifted over the years. There have been a few rare occasions where I had to use a Chromium-based browser, and I felt the same "ick" I used to feel when forced to use Internet Explorer for some reason.
Come to the Firefox (and variant) side. The water is warm.
I have a completely custom minimal layout with address bar and tabs at the bottom, all the extensions I need, and I don't notice the performance or compatibility differences almost ever, with few rare exceptions. I feel it much more as "mine", and it's a joy to use.
Not sure I understand the statement - what are you using?
Mostly because they're peeing in the pool. Mozilla deleted their promise to never sell its users' personal data.
One can even self-host their own sync server if so inclined.
Mozilla has done plenty of bad things and they rightly deserve criticism, but options in the browser space are few and Mozilla is considerably less bad than Google. And other Chromium browsers perpetuate Google's control over the web. If you're going to complain about Mozilla when someone recommends Firefox, at least offer a non-Chromium alternative like LibreWolf (or maybe Ladybird someday).
It's a browser.
