Firefox crashes upon startup. The Crash reporter says something about FF having trouble restoring windows/tabs. I restart a couple of times and then FF comes up and I have to co through customization each time. I tried: complete removal of FF and clean reinstall: did not help. Currently I use FF English-ZA, but found the same problem occurs with other versions. Also tried to switch off this DEP - to no avail. So what is going on?

It apparently was the hardware acceleration Thanks!

I still have to add: I have 3D vision with a NVIDIA Quadro 2000D graphics card, driver version 320.92
