I don't know if Firefox can do that but I have a Dell XPS desktop running Windows vista. Up until a few days ago, i had no problems. Then I had noticed that Firefox kept crashing. Sometimes that would accompany a system wide crash where I wouldn't get the BSOD but a blue screen that said that Windows was shutting down to protect the system. MacAffee did detect an issue and that was quarantined and I ran my My McAffee antivirus software afterwards and no infections were reported.
What I notice now is that my system occasionally crashes but mostly when Firefox is running and usually it reboots. I had used the Firefox reset tool and the problem persists. I have the most recent version of firefox installed. I was just going to my address book in Optimum Webmail and the system crashed so I'm wondering if there is a connection between my online activity and these crashes.
I am trying to avoid reinstalling Windows from the Dell recovery disk as I would lose everything on my hard drive. I am not sure where the drivers are and would want to save them as I have saved all my data files on a thumb drive.
I am going to call Optimum right now and have them troubleshoot my system to see if there is an issue with their software but the problem happens with Firefox too so I"m not sure what is happening
