Hi. Dell Inspiron 1420, Vista and Firefox 3.6.3 Cannot open firefox at all, it starts to load, then crashes. Happens everytime. Also my IE is crashing. Only way I managed to go online was by finding an old PC World disc (2005) that had an original version on it. Is this a new virus I may have picked up? Or is it a glitch? I installed 3.0.6 thinking maybe it was the latest version of Firefox having issues, but that crashed immediately also. == Operating system == Vista
