I still don't understand what problem you guys have with Firefox. I really don't, and comments like yours are always very vague and seem to assume that it's obvious.
For me Firefox is (slightly) better than is used to be, not by a wide margin but it's not gotten worse either.
I've been running it since it was Phoenix so I think my experience is at least somewhat valid, which is why I'm so confused by these comments.
You’re not alone. Been a user for years and I still don’t get the hate.
Having said that, I keep a copy of Ungoogled Chromium for those websites that refuse to test against FF.
Are you referring to technical implementation or the poor anti-privacy decisions they keep making when you say 'slightly better'? I have not given up, but I am profoundly disappointed and for somebody who says they have used FF for so long, it feels like I am being gaslit when you say they are peachy.
People have problems with what they choose to program, not the quality of their code. I too have used FF since the beginning, but switched to Waterfox last year (it took me about two years to make that decision - I didn't make it lightly). I chose WF in large part because its profile remains compatible with FF so I can switch back if they calm the F down and start acting normal again for long enough to rebuild some trust.

Also go to the website of any one of the FF forks and read their reasons for existing. For example:
