When I try to open firefox, it says it is already open and tells me to close it but its NOT open and I want to know how to quit it so I can actually use firefox
It says that it is open & I need to quit it before I open it again. But it isn't open! How can I quit it so I can open it to use!?

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles.
NOTE: Establish a habit of exiting/closing Firefox with Firefox button > Exit or File > Exit to allow an orderly shutdown of Firefox and closing of all of the files that Firefox has open.
- Stop the Firefox process:
- 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 an Extension or Plugin causing the problem

Firefox is somehow running in the background - maybe because it didn't shutdown correctly. You can close it using Windows' Task Manager:
- right-click the Windows task bar
- click Start Task Manager
- go to the Processes tab
- look for firefox.exe
- once you find it, click it and then click the End Process button
Now you can try staring Firefox again. Be careful not to end other processes, though.
