User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:35.0) Gecko/20100101 Firefox/35.0 Build ID: 20140911064110 Steps to reproduce: After the latest Nightly version update (35.0a1 (2014-09-11)), Nightly asked me to test e10s. After restarting, I tried playing a youtube video - specifically http://youtu.be/Q3L4spg8vyo. Actual results: Audio was playing fine, but video is completely black. Expected results: Video should have played. I tried two things - using a non-e10s window, and the video played fine. The second thing is I checked out http://techslides.com/sample-webm-ogg-and-mp4-video-files-for-html5/ - mp4 wouldn't play video (but did audio), ogg and webm played fine (audio and video). I've also tried disabling the only plugin I have (LastPass) and it seems to have no effect.
I think this is a duplicate of bug 1064847.
