FF does not start. FF does not work on any other user accounts on this computer, but it works fine on another pc on our home network. Thanks for any help you can offer.

The computer is a HP Envy 17 laptop. Firefox does not appear on the list of the Manager of process tasks or applications. System Restore has not fixed the problem. Google Chrome works well. Internet Explorer works well until I tried to download Firefox. Then it crashes too. This pc work Firefox very well since I bought it 10 months ago. I upgraded FF3 4 then 5 with no problems. All of a sudden yesterday it stopped working. There is no error message and of course FF does not start because there is no list of Firefox in the process tasks or applications Manager. I tried to uninstall Firefox, then tried to download usingInternet explore, but when I click on the download button on the site of Mozilla, Internet Explorer crashes. I did a system restore to 16/08/11 when Firefox was still working. This restored the program but it still does not work. Google Chrome seems to work very well. My internet access is through wifi via a Verizon Fios Actiontec router. I use Symantec Endpoint Protection against the virus and make having all programs Norton or Skype do not appear in the Panel. My pc is set for automatic updates from Microsoft and HP. They both say that my software is up to date. Y at - it a fix for this problem or is it a sinister plot by Microsoft to force us to use Internet Explorer?

Download Firefox using some other browser (Chrome, Safari, IE) of one of the mirrors here:
