 > > Upon further thought I wonder whether the approach in my patch is
 actually a good one. I mean we don't set `media.webm.enable` to `false`
 either to get WebM videos to adhere to click-to-play governed by NoScript.
 I fear we are essentially breaking MSEs on higher security level this way
 instead of making it click-to-play.

 work correctly when both noscript.forbidMedia and
 media.mediasource.enabled are set to true?

 Yes.
