Today FF updated to 8.0, and suddenly the browser would no longer go back a page, no matter how many times I press the "left" button, or even if I right click on it and try to go back to ANY page. It appears like it tries to do it, flashing the page a few times, but then remains on the page I was last at. Unfortunately, this problem occurred in the same time frame that some Windows updates were taking place, so I figured I'd first try to go back to FF7. This did not fix the issue. I uninstalled FF7 altogether, and reinstalled, leaving personal data on the HDD. This did not fix the issue. So I again uninstalled, and removed all personal data as well and reinstalled. I even went through the freaking registry to find any Mozilla leftovers, just in case. No addons of any kind running, assuming a completely clean install, this did not fix the issue either. So I did a System Restore on this computer, going back about 16 hours to a previous restore point. This did not fix the issue. I've done several virus scans and can find no infection. I'm at a complete loss. I cannot figure out why suddenly I can no longer go back in browsing on FF, in any tab. Only forward. Any suggestions would be definitely appreciated, thanks in advance!!
