I can no longer play videos in YouTube. I am running Firefox 37.0.1 (MAC). This is a new problem, most likely occurring in the last 24 hours. YouTube videos are working in Chrome.

Start Firefox in Safe Mode {web link} While you are in safe mode;

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?


If you have problems with current Shockwave Flash plugin versions then check this:
