Steps to reproduce:

i went into about:config to put 'false' into media.autoplay.enabled  because i don't want any autostart video (media, audio or animation).
then i tried 2 examples :
https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_video_autoplay
http://www.html5videoplayer.net/html5video/mp4-h-264-video-test/


Actual results:

well ,for both the videos, there are no autostart ! 

but....

in the 1st example (w3schools), the mp4 file is fully loaded !!!
whereas in the 2nd example, the stop-loading is normal.



Expected results:

when autostart is disabled,  there should not be any load of content at all.

imagine the video size is huge like many MB bytes !

i know it is not the right place, but maybe...
For 15years of seamonkey i was always needed a feature like "Block videos from %domain%" like the super feature "Block images from %domain%" which is already in seamonkey.

So, putting "false" into "media.autoplay.enabled" config  may be the way to block any loading of video file in webpage (and autostart too).
My bandwidth's masters will appreciate & valide such a feature !

We may want to load a little bit to let users see the frames quickly when users want to play it. But we also don't want to download too much data since users may not like to watch it.

I don't think it's a issue related with autoplay.
The video would still be loaded even the video doesn't have autoplay keyword, it's depend on the attribute  "preload" of the media element.
If you won't want to load too much data, maybe you should change the pref "media.cache_size" to smaller value, or change the pref "media.preload.default" to 1 (no-preload).
