I am working with Firefox with multiple tabs open, and 2 instances of Firefox on desktop. I close out of Firefox completely, and later when I want to bring it back up it will not load because there is an instance of it running already. That's when I go into the task manager and find at one or more instances running trhat I manually close out.

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles.

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 and Extension or Plugin causing the problem

You may need to update some plug-ins. Check your plug-ins and update as necessary:
