That is called "hang at exit" and can be caused by a number of issues, including an Extension or a Plugin. Look at the following.

Stop the Firefox process (you already know how to do this):
- Mozillazine - Kill application
- Windows 7 users click here
- Mac users: http://techheavy.com/2011/02/the-mac-task-manager/
Why Firefox may hang:
- Firefox hangs (see Hang at exit)
- Firefox hangs (Mozillazine) (see Hang at exit and Closing Firefox properly)
- Firefox is already running but is not responding
Use Firefox Safe Mode to find a problem with an Extension or Plugin:
- Don't check anything when entering Safe Mode, just continue
- If the problem does not occur in Safe Mode it is probably and Extension or Plugin causing the problem
