Expected results: Sound should play all the way to the end. Which it does if Flash player is used instead of the HTML5 player.

Happens in Chrome too, so probably a youtube bug not a Firefox one.

Ok. Apparently Youtube now serves HTML5 to IE too. And surprisingly IE manages to not cut off the end. Well if IE can do it, why not Firefox. so reopening..?

The end of the audio in https://www.youtube.com/watch?v=rh8m2-q71qQ is cut off for me in IE Edge (and Firefox and Chrome). I get "A few" in all three. Same with the other video. Curiously, if I download the MP4 and WebM versions with youtube-dl, less of the audio is cut off. I get "A few moments later" (but it cuts mid-"r"), so the actual media is longer and plays fully in VLC, Firefox, and Chrome. Same with the other video. So this does look like a YouTube-side issue. What video and IE version were you seeing complete playback with?

https://www.youtube.com/watch?v=7LlIKtQwIxI Windows 7, IE 11, i can clearly hear all of "unbearable faggots" where as in Firefox all i hear is "unbearab"
Hitting refresh gives me different amounts of audio each time.

If I disable MSE by setting media.mediasource.enabled to false, I get consistent playback of all audio... could be a timing/buffer appending issue with the MSE player.

Well i just found out the "Magic options" addon causes this. Its "auto replay" option restarts the video before it reaches the end. If i disable it the problem goes away. Other addons which have this option might be affected too. Anyways, marking this as resolved because its not an Firefox bug.
