I get the following message every time I close firefox from File/Exit, and try to open again: 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. I have to re-start every time.

See "Firefox is already running but is not responding" error - How to fix. It sounds like in your case Firefox is not closing properly, in which case the "Hang at exit" section of the Firefox hangs or is not responding - How to fix article is relevant.
