Comment (by i139):

 Replying to [comment:38 ma1]:
 >  That's way I believe restricting MSE usage as an additional permission
 for the site (or the webpage, as I said, for convenience rather than
 security, e.g. on Youtube) is the most sensible approach: exactly the same
 NoScript already adopts for WebGL.

 is the best option how we have now.

 however saying about js and codec is proper make a statement about firefox
 codec, in firefox 51 mozilla adding support to flac, noscript or torbutton
 could use a serie of checkbox for codec or for media format, avoiding
 unnecessary and unsafe codec/format adding a extra protection for user
