Firefox hangs & crashes on Mac OSX - Solved!

If you're reading this, you probably have at least one of the issues I had with Firefox on Mac OSX.

In short, there are two problems that can absolutely cripple Firefox on the Mac (Intel MacBook in my case).

1. Anti-Phishing tool causes browser to hang, presumably while checking with a server somewhere about the pages you are on. I found this one widely reported on the web and it did improve my FF for a while.

2. Corrupt profiles. If you can live with re-installing your plugins, and exporting / importing your bookmarks, this is an easy fix to try. It took me about 2 minutes to complete the fix for this. All you have to do is:
* Organize bookmarks, then File -> Export bookmarks (some file)
* Quit FF
* Remove your profile folder from Mac HD -> Library -> App Support -> Firefox (I removed this entire folder)
* Start FF, then import bookmarks from organize -> import (same file)
* Finally, add any plugins you want again.

#1 removed some of the spinning beachballs of doom, while #2 completely fixed FF in my case.

Hope this helps someone out there. Cheers!
