This message comes up when I try to open firefox. I have looked at all the siggestions on the web and thothing works. I have gone in to task manager and it is not running. I even removed it and re-instaled it. No luck. I just had an new update download to the computer before I shut down last and I am now runing Windows 7 Home Premium 64 bit.
