I want Firefox to be better. I've gone back to it many times in 20 years. I'm using it right now.
But I tend to always leave at some point due to performance issues that I can never resolve. I'm having a good run at the moment with the worst of it being a random lockup I can't seem to figure out the cause of (and is pretty much just a task manager close, reopen, and resume...and infrequent enough to not really cause much headache)
But other times i've had memory leaks, or using most of the ram, or terrible addon management. I pretty much tried Chrome in the first place because back whenever Chrome came out, Firefox was using so much memory that I couldn't play games while Firefox was open, and multitasking is one of the things I've always taken as the reason to play games on PC over consoles.
All in all, I think it represents something better, but whether or not it is better is always up in the air. I just hope people stay hard on them to keep trying to improve the system, because i'm sure there's people far further on the fence than I am, and I think firefox is capable of just being a good browser.
