I am on windows 7 and I upgraded to the newest verison of firefox and now it will not open. I have removed firefox completely and uploaded it again and that did not work. I then made sure it could get through my firewall and that did not work. So my latest attempt I removed firefox 10 again and uploaded the beta version hoping that would do it and once again nothing. It will not open at all. Please help - is there a live chat or a number to talk to someone at Firefox?
I think when uninstalling you may also have to choose (tick) to delete the preferences and other personal data like the bookmarks, stored passwords etc. to erase completely. If you are installing afresh, please try right-clicking on the file and '''Run as administrator''' to install. And when uninstalling, please also make sure choose to delete all data and also manually delete any '''Mozilla''', '''Mozilla Firefox''' or '''Firefox''' from %appdata%, %localappdata% and %programfiles%. You can open a location by typing for eg. %appdata% in the '''Run''' box (Windows key + R). You may also have to check the '''VirtualStore''' folder in %localappdata%. Files in the VirtualStore can be problematic. I think a clean installation may help.

Please note that using system restore would usually damage the Firefox installation.
