Yeah but Mozilla has been getting shittier and shittier as time goes on. I think it all started when they forced extensions into FF without the ability to remove them, only to go into the settings and disable them (which doesn't even fully work). And most of the de-Mozillafied alternatives (like Waterfox which pretty much the only benefit is no Mozilla telemetry) have a lot of their own problems assuming you want a normal casual browsing experience (so no Librewolf or Tor)

Mozilla's better than e.g. Google or Microsoft but at the end of the day they're still a company that often makes anti-user decisions (although being technically non-profit helps them be significantly less bad). They've started converging towards those companies in a lot of ways, and they've been trying to make the browser more like Chromium browsers equally as much.

Also due to their bad priorities FF is noticeably worse in a lot of ways thab e.g. Edge (as in performance/resource usage by a long shot)
