I've looked around a bit for an answer to my problem, but haven't figured it out 100% yet. Firefox 3.0.4 is beginning to run like total garbage on my Mac. It constantly freezes for a couple seconds and then resumes. This takes place while scrolling through pages, loading pages, and even playing videos on YouTube (it can get really annoying there). I believe that one solution would be to delete the ~/Library/Application Support/Firefox folder... but that will also get rid of all my add-ons, bookmarks, preferences, etc. Is there anything else I can do to make it run better again? I find myself having to switch to Safari all the time to get some relief from this issue. I need Firefox though because of some add-ons I use. Thanks!
