Build ID: 20161122030216

Steps to reproduce:

Well this issue came with new release of Nightly.
Without any change from my side.
No new add-on, no new extension, nothing changed. Just regular automatic update.


Actual results:

Its like 99% of YouTube videos cant play on e10s window.
I found very few that work but unfortunate i did not make a list ... but found again at least one.
Screenshots are in attachment.

https://www.youtube.com/watch?v=AIjm8W_4qz4&list=RDAIjm8W_4qz4 is working
https://www.youtube.com/watch?v=gzbTXQlxuyo and almost every other is not working

I tried to disable add-ons and extensions, no change.
I tried to search for similar bug, but did not find any with similar description.
If i open non-e10s window from menu or disable multi-process firefox, there is no issue.
This issue is on both my computers, on multiple connections from multiple ISPs.
On both my computers i have my Sync account in use.


Expected results:

Well, all youtube videos should play just fine :)

Your Nightly is old.
Try latest one. Bug 1318083 should already fix this.
