Firefox comes up with ' is already running....close and restart', but no visible firefox is running and even in task manager it is not running. How do I 'stop' firefox? Restarting the computer did not help

This happened

Just once or twice

User Agent

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)
