I believe it started when firefox 32 updated. But suddenly every time I try and play a video in Netflix the screen is just black. If I log out of netflix and log back in, it will play once, but if I try and play a second movie, choose something different or close the browser I get a black screen. I have tried the following to resolve: -Safe mode. The movies WILL play in safe mode, but trying to disable all extensions and add-ons still doesn't work. -reinstall silverlight -reset firefox -change cookie settings. delete all cookies and cache - turn off hardware acceleration I just CAN NOT find this problem!
