I can't get Firefox to start up. I've downloaded a new copy several times and keep getting the error message, "A copy of Firefox is already open. Only one copy of Firefox can be open at a time". I do not have Firefox running anywhere.

See "Firefox is already running but is not responding" error - How to fix, the image shown in that article is the Windows equivalent of the error message that you are receiving, but the information relates to the Mac.
