Post your Graphic section from about:support,
next make sure that you're using latest GPU drivers,
if not, update it and redo the STR and post info from about:support again.

Here is the printscreen of about:support, Graphics section: http://i.imgur.com/M3Cgz49.png
I have the latest driver for my GPU.

I could not reproduce this issue on Windows 7, tried using the latest Firefox 50 release and the latest Nightly 53. 

Iulian, have you  ever seen this issue on other Firefox versions prior to Firefox 50? Does this happen every time you watch a YouTube video or is this something intermittent? Would you be willing to try to narrow down the regression window? You can use the mozregression tool from:
http://mozilla.github.io/mozregression/

After seeing the video with the artifacts, this feels to be more a Graphics issue than a Video:Audio one. Anthony, could you please take a look?

It started around Firfox 48 I think. It's quite random, but I would say if I watch a video for like 30min there is a 70% chance of it appearing. First I was thinking the same, a graphics card issue, but I don't get this problem using Chrome and I play games, quite graphical intensive ones, and don't have any kind of problems. I've even tried OCCT as stress test to see if those artifacts are coming up and nothing. This only happens while using Firefox and watching videos on Youtube or Twitch.

Could be something related to AMD gpu drivers, there was a time when you'd get graphical artifacts on the interface of Firefox and disabling Hardware Acceleration was fixing that problem back then, but it was fixed at some point. I've tried doing the same now, but still I get those artifacts.

I must say I'm not familiar with Mozgression tool.

It looks like a graphics issue to me.

Just wanted to let you guys know that now I'm running Firefox 50.0.2 and I've installed the latest AMD driver that was released like 2 days ago which included some fixes for Firefox. It seems to work fine, no artifacts. I'll keep you updated if they appear but it seems to be fixed.

Per Comment 9 marking as WFM.
Reopen if it will happen again.

Seems the problem came back while watching Twitch for a few hours. My initial testing was with Youtube and didn't had problems until now. Feels like Twitch is causing this problem, might be something related to their implementation of HTML5.

Nothing changed from last time in terms of drivers or add-ons.

Have you tried disabling hardware acceleration?

I've tried that and still got the artifcats. Btw, could be the fact that I enabled Electrolysis?
I set:
browser.tabs.remote.autostart to true
extensions.e10sBloc­kedByAddons to false
extensions.e10sBloc­ksEnabling to false

Milan, a GPU issue?

Comment 15

[Milan Sreckovic [:milan] (needinfo for best results)]

This looks like an actual hardware issue, yes.  Probably seeing it with movies and Firefox more because we're using more graphics memory.

I couldn't manage to reproduce this issue. Since the bug was logged 5 years ago, most likely isn't reproducible anymore for the reporter also.
Closing this bug as resolved: Worksforme.
