Having used the beta 4 version of Firefox, the screen pop up kept insisting to upgrade to the 4.0 beta 5 version. I finally went ahead and did the update, and have had the above issue since.

Firefox 4.0 has not been in Beta testing for months now as it was released back in April and you appear to be posting with Firefox 5.0

Are you using the Firefox 5.0 which was released June 21 and is at www.mozilla.com ?

As for the sudden reboots well it could likely be a issue with hardware or dirver (for graphics card for example) or even a runlevel software as a application like Firefox itself does not cause Windows to reboot.
