A little note for those using Firefox browser. The latest update of an Intel driver apparently caused my browser to hang after several hops across the internet, particularly in graphics-heavy sites. This would produce an error message in Win 10 to the effect that firefox had been blocked from accessing graphics hardware, and the program would hang on the next requested hop to another site.

The cure for it apparently was to go to the video adapter on the hardware list and roll back the last update. We’re not totally sure this fixed it. But so far no more hangs.

Dunno if it’s Intel’s problem or Mozilla’s, but the two aren’t playing nice with each other.
