Try running firefox in safe mode.
Menu -> Help -> Restart with add-ons disabled -> Continue in Safe Mode.
If it works in safe mode, then one of your add-ons is causing the problem.  The only way to troubleshoot this is to disable all add-ons, and re-enable them one by one to find out which add-on is causing the problem.

If that doesn't help, create a new profile to see if it helps.  You can still keep your current profile so creating a new profile won't cause you to lose your bookmarks, passwords, preferences, etc.
