I am not using Firefox at the moment, but my computer indicates it never closed and is still active and all attempts to get it to close have been unsuccessful.
I downloaded a file while in Firefox. I went to my documents to be sure it had downloaded and when I tried to click back to the email from which I had downloaded (in gmail), I could not access it. Every attempt to exit Firefox after that was unsuccessful. It takes several tries to close down my computer. I have clicked End Program repeatedly, restarted, hard-stopped, unplugged, tried ctl/alt/delete and ending program, tried to uninstall program--all without success. When shutting down computer, I now get message that XTRay.exe and appupdater.exe are also running. Tried to stop XTRay via Task Manager and never found appupdater at all. It doesn't matter. Firefox still will not stop running.

XTRay.exe and appupdater.exe aren't part of Firefox. Sounds to me like whatever you downloaded may have carried an unexpected "bonus" with it and now you PC is infected with a virus or trojan. Run a full, deep scan with your Anti-virus application.
I've run three scans and all come back clean, but I'm still not convinced they are. If this is something new, there may not be a fix yet. Thanks for the advice.
