trouble closing firefox

more options

Lately whenever I close Firefox my computer tells me it is still running. (For instance, I close down the browser, but leave the computer on, then click to open it later and it says it's already running so I can't open it). Then I'm forced to either restart the computer or use IE. I have Windows Vista.
