I’m running Firefox 220.127.116.11 on my (relatively) new (intel) Mac. Problem is that Firefox locks up several times a day. I found a forum which suggested disabling the anti-phishing functionality. Several people seemed to have benefited from said disabling.
I also found a Bugzilla report about the same behavior. It sounds like the anti-phishing thing can cause some problems during startup, but is probably not responsible for hanging during regular browsing. My problem is not on startup, but on browsing, so disabling anti-phishing probably won’t help me. But I’ve disabled it just on the off-chance that it will. If this hanging persists, I’ll either switch to Opera or Safari.
What are your experiences with FF on Mac? Crashes, hangs? Or is your world just peachy?
