I switched from Google Chrome to Mozilla Firefox yesterday and got a problem with some formats of video. I think, this is MP4/H264/HTML5, because in Twitch.tv player isn't working fine (audio works fine, trouble only with video), when player in "HTML5 Player mode", i got greenscreen. But when i change the player by function of Twitch, it working okay. So, same with YouTube. Some (not all) videos got greenscreen, live translations got greenscreen. Its not a problem with Adobe Flash. I think, this is because of HTML5 and MP4/H264. What i have to do? Windows 8.1 Links of cites i tested: https://www.twitch.tv/ https://www.quirksmode.org/html5/tests/video.html https://www.youtube.com/watch?v=hHW1oY26kxQ

click on the link and it plays just fine but there alot of ads popping up in it as my adblocker is killing those ads on Twitch. And the second quirksmode opens just fine. YT is no problem. So what else for addons or security or adblocker do you have installed?

Hmm, Firefox requires Media Foundation for MP4/H.264 decoding. Could you check this article as the next step: Fix video and audio problems on Firefox for Windows N editions.

If Firefox can decode but displays green, this sometimes is an incompatibility with your graphics card driver software. Please see: Upgrade your graphics drivers to use hardware acceleration and WebGL.
