I close all Firefox windows. When I try to open another window later I get a message telling me that Firefox is still running and that I need to close all windows or restart my computer. I have this about 3 times a day this past week but prior to that it was maybe every one or 2 weeks. I had the 3.5.10 Version of Firefox, but have just updated to see if this stops this from happening. But what do I do if it doesn't stop it?
