BTW, I can also reproduce the problem on Google Chrome Dev54, Windows10.
Looks like it's not a Firefox regression, because the same issue is reproducible on Firefox 48, but sometimes you need to redo a STR one or more times to see the bug.

Per Anthony's comment in #6, the issue is being tracked and appears to be within Youtube.

Karl, can you contact YouTube to follow up (when you're back from PTO)?

I'm not sure I understood the steps to reproduce, so I did with a practical example.


0. Not logged in.
1. Go to 
Gnarls Barkley - Crazy
 https://www.youtube.com/watch?v=bd2B6SjMh_w
2. Remove autoplay
3. Going to https://youtu.be/bd2B6SjMh_w?t=181
4. I get a mosaic of six tiles for the next videos to play.
5. Searching for "Amy Winehouse" https://www.youtube.com/results?search_query=Amy+winehouse
6. Click on https://www.youtube.com/watch?v=KUmZp8pR1uc

I got before the ads a very quick flash with the old frame of Gnarls Barkley - Crazy

So I guess this is the bug, the very quick flash with the old first frame. It lasts less than one second. 

Reported through the partner mailing list.

YouTube acknowledged the issue.

> This is indeed our bug and I think it's caused because of the way we reuse video tags. It should be fixed in an upcoming version of the site.

WFM - is this issue still reproducible?
Flags: needinfo?(virtual)
Yes. The issue is still reproducible and still not fixed by YouTube developers for over 3 months, same as bug #1300235.

Anthony, Adam Stevenson was able to reproduce this issue. Any thoughts?

Mike I read this bug over again today and am thinking this isn't FF specific so doesn't really need Anthony's attention right?
Flags: needinfo?(ajones) → needinfo?(miket)
David, not sure if this matters but it's in fennec 55 that I see this issue daily. Each new video displays the frame from the last one for a second.
