Why is my Firefox running in "stealth mode"?

Posted

Many times when I close out of a web page and I go to restart I get a Message telling me "Firefox is already running and I must close it out before I can start another web page, but I have already closed it out and there is no Firefox web page there to close out as I have already closed it out. Sorry for all the "closing outs" but that's the only way I could figure to explain it. Any help would be greatly appreciated. Thanks!!
