I have no idea if it's related, but it seemed to happen right after I did it. The page starts to load, then I get the uh... spinning colourful thing (Mac equivalent of the hourglass) while it loads the rest, I can't even scroll the part that's loaded, click links or anything. It only hangs for a couple of seconds but it's starting to bug me. I've tried deleted the app and reinstalling while keeping my profile/bookmarks/settings but it didn't help. Anyone got a solution? If you came in here to moan about Firefox, go and find something constructive to do. It works fine, I've just messed it up somehow...
Looks like you're not the only one who's been having troubles with Firefox. Here's another couple links I found, in case any of their suggestions work: http://discussions.apple.com/thread.jspa?threadID=2624348&tstart=165 http://support.mozilla.com/tiki-view_forum_thread.php?topics_offset=13&topics_sort_mode=hits_desc&forumId=1&comments_parentId=2659 Sorry I can't help you directly; don't have a Mac myself.
Seems a few people there are blaming Flash... I've never had a problem with it before so if this is the start of a rocky relationship I'm gonna be mighty pissed.
