Why do I have to FORCE QUIT Firefox EVERYTIME I attempt to shut down computer?
I have disabled ALL add-ons, I get hung up when trying to clear cache and cookies. When closing Firefox it requires that I FORCE QUIT in order to shut down computer. WHY, I will soon change browsers if no solutions soon.

If Firefox hangs (stops responding) when you try to clear the cache and cookies and you have already disabled all Extensions and Plugins from the Firefox (Tools) Add-ons manager, then the problem could be one of the files in your Firefox profile. See Firefox hangs or is not responding - How to fix and try creating a new Places database, by opening the profile folder (via "Help -> Troubleshooting Information -> Show in Finder"), then quitting Firefox, and deleting the file(s) places.sqlite and places.sqlite-journal (if it exists).
If that doesn't help:
Try creating a new Firefox profile for testing (this will not remove your existing profile ; you can choose between the two in the Firefox Profile Manager). See Profile Manager - Create, remove or switch Firefox profiles for details. For other ideas, see Troubleshoot and diagnose Firefox problems.
