I experienced a crash yesterday and since then the shortcut to Firefox (the shortcut created by Vista itself in Start menu properties/Customize/Internet Link) says it's not a valid WIN32 application. When I click OK it says the program has been moved, renamed or deleted. Clicking the actual firefox.exe works fine though. I even did a clean install of Firefox but Vista keeps coming up with this error. Changing the link to Internet Explorer works fine.
It can easily be solved by manually creating a Firefox shortcut but i was wondering how I can fix this problem the right way.
