Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system. How do I fix this? I am ready to go back to internet explorer!

This box appears and then firefox quits...never opens. I have uninstalled, and loaded firefox 5 times and never got it to run.
