Arguably Firefox has never been a bad browser, at least technically speaking for sure. But instead of staying the leader, they started to trail Chrome unfortunately. And of course, on Android, they messed it up big time when they switched to Quantum, and stopped supporting most extensions for years. (That was when I switched to Samsung browser, and realized that it is pretty much the best one on Android - after Firefox 68, which got pretty old after a while). Of course I'm still a Firefox user on Desktop (and I also support them with code actually in the embedded space), but I consider them a wasted OSS opportunity.
