Attachment: youtube_window_ff_42.JPG

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20151029151421

Steps to reproduce:

I simply upgraded Firefox 32-bit to version 42.
Then I went to https://www.youtube.com/  and started watching a video.



Actual results:

I saw a black line on the video (see the two screenshots attached).
It appears on all the youtube videos only when the controls are visible.


Expected results:

I should see videos without a black line like with firefox 41.
