So let me get this straight - Firefox locks up when you try to browse? You've got any addons installed? If so, which ones? Try going to Help > Restart with addons disabled.

Almost forgot - back up your bookmarks. Go to Firefox > Bookmarks, then under Import and Backup, click Backup. (Just in case)
