Earlier quoted context omitted.
What state is that? I’ve been very satisfied with FF over the past 5 years.
Not sure how much of this is living in a bubble or selection bias of negative experiences in common but my own impression of the firefox userbase is that a significant portion of it are using firefox as a "least worst" browser, rather than one they are actually very happy with.
I'm pleased to see others have good experience with FF performance, but for me, the performance simply became unacceptable.
