Firefox will not open - it says it has a copy open already - and it does not. This happened after I tried to update to new firefox.
I attempted to upload the new version of Firefox. When I did this - I could not open Firefox at all - a box pops up telling me to 'Close Firefox - a copy of firefox is already open - Only one copy of Firefox can be open at a time.
I tried to remove Firefox completely form the computer and reinstall - and I get the same message.
I am using a macbook prop with Lion operating system

Must be the "hang at exit" problem. You already know how to do Step1; now just determine which Add-on (Extension or Plugin) is causing the problem.
- Stop the Firefox process:
- Mozillazine - Kill application
- Windows 7 users click here
- 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
