I've had significant performance problems with Firefox recently. It's always felt less snappy than Chrome, but it got much worse these past few weeks -- every time I try to close a window, it would freeze with a busy spinner for 3+ seconds, often 5-10 seconds. I did a profile refresh last night and I think it's resolved the primary issues (despite retaining all my extensions). If it hadn't, I would have seriously considered switching to Brave or Chrome. Ideologically, I believe it's very, very important to support Firefox, and I also think the work they're doing with the Stylo, Quantum, etc. is very exciting, but performance issues with the UI itself got me off of Firefox for years once before, and almost did it again recently. (The first time it happened it was shortly after they started using sqlite, and I suspect that both of these instances were sqlite/profile data issues.) From my own personal experience, UI speed (partly influenced by "bad" profile data) is the area where Firefox is failing, and the only thing that keeps me from unabashedly telling everyone I know that Firefox is better (user-experience-wise).
