how to disable ALL html5 media features?

[zenewbie]

I'd like to make sure that no video will be played when going to a youtube page, but disabling flash alone doesn't do it any more. I cannot disable everything because I still need to be able to post comments and stuff, so only the media portion of the html5 elements should be disabled. How do I do that? In standalone Firefox Browser it's possible by disabling the html5 plugin, but in ZP?

1.go to "C:\Program Files\ZennoLab\ZennoPoster Standard\Progs\XulRunner\greprefs.js"

2.backup greprefs.js

3.set to false the properties:
pref("media.windows-media-foundation.enabled", false);
pref("media.windows-media-foundation.use-dxva", false);
pref("media.windows-media-foundation.play-stand-alone", false);
pref("media.raw.enabled", false);
pref("media.ogg.enabled", false);
pref("media.opus.enabled", false);
pref("media.wave.enabled", false);
pref("media.webm.enabled", false);

4.turn off flash in your project

good luck!
