Cannot view any videos. Get a green screen instead.
I've tried several sites (YouTube, Facebook, PlannedParrothood) and all of a sudden they have all stopped working in playing videos. I get a bright green screen throughout the entire video, but can hear the audio and can also see the thumbnail of the progress bar playing. I'm using version 31.0 on Windows 7Pro. Videos worked properly until today.
