Sometimes when I close Firefox and then try to reopen, I get a message that "Firefox is still running" and suggests I close it (which I have already done) or restart my computer, what do I do?

I really have had a problem with Firefox responding sluggishly for the last 6 months or so. I have difficulty opening it, closing it properly, freezing up. I don't have this problem with other programs, so don't know what is going on. Also I can't use my latest version....10 of Adobe Acrobat now. Dont know if that is my computers fault or Firefox. Any help will be appreciated.
