I cannot access Firefox all of a sudden - I get the message c:\Program Files\Mozilla Firefox\xpcom.dll is not a valid Windows image and Firefox won't launch and I cannot upgrade via IE
Firefox was working fine unti today when I received the above message when trying to launch. I have tried to upgrade (obviously via IE) and that doesn't work either. Mozilla site says it cannot find the web site/download file

download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
Don't remove personal data when uninstalling.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
