Video autoplay workes in Chrome, Opera and Edge. No video at all in Safari.

FWIW this does work for me on Nightly. It's possible it was broken back in 48. Unfortunately I can't help further with media stuff so I'll leave this to the media folks.

<video width="32" height="24" autoplay>
  <source src="movie.mp4" type="video/mp4">
  <source src="movie.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>

True the FF adon FlashStopper https://addons.mozilla.org/en-US/firefox/addon/flashstopper/ also stopps other Video formats.

OK it plays but reloading the video with Javascript to keep it endless playing showes white in between. Same in Chrome. That looks bad and is not a good workaround for the GIF bug https://bugzilla.mozilla.org/show_bug.cgi?id=129986
