When I exit Firefox, it continues running in the background. How can I prevent this and keep it from happening apparently by default?

I know that Firefox continues running in the background because after I exit the program, I use CCleaner and it indicates programs are still running: Firefox. This happens every time I exit Firefox. There seems to be a default mechanism to keep it running. How can I prevent this?

Check and tell if its working.

Thanks for your help! These work. I do wish that this wasn't an inherent problem in Firefox that occurs all the time, but I guess that's up to Mozilla and contributing programmers.
