the thumbnails all play automatically at the same time, and the website gets so slow it's impossible to use.

NSFW. spin-off of

All individual thumbnails on the home page of

are on the form of:

<video defaultmuted="" loop="" disableremoteplayback="" autoplay="" muted="" playsinline="" style="width:100%;height:100%;position:relative;top:0;left:0;" id="thumbPlayer" class="img-fluid" poster="">
<source type="video/webm" src="">
<source type="video/mp4" src="">

On Firefox Android they fail to play. I suspect the first source is tried and it's not working. But it should probably fallback on the second, but it doesn't seem to work. While it is working on desktop responsive mode with Firefox Android UA.
