Created attachment 8529410 [details] Capture.PNG User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0 Build ID: 20141113143407 Steps to reproduce: Will be difficult to reproduce, but it happened while watching a youtube video: http://www.youtube.com/watch?v=Y8ygKnBtKAk Actual results: The song started playing well. But, mid-way became choppy. The html5 video frame had missing layout elements (see attachment) and missing video too. Expected results: The video should have been displayed along with the video controls.
I didn't managed to reproduce this on the latest release(43.0.2) nor the latest Nightly(46.0a1).

When doing this, you could create a new clean Firefox profile, or maybe test in safe mode, as some of this issues may be caused by third party installed addons or custom settings (https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems). Thank you, Vlad
I really doubt if it'll be worth the effort to try this since I haven't seen this happen for several months. In fact, I was never able to reproduce the bug as such. It would just happen once in a while and I haven't observed any set pattern for the occurrences.
Due to the fact that I cannot reproduce the issue and also the reporter cannot, I will mark this issue as RESOLVED - WFM.
