So recently I built a PC. I installed firefox and cannot seem to get HTML 5 video working. I enabled webm in the config to at least get HD on youtube however without that I'd be stuck at it only loading in 360p. When I go to the HTML5 test page from youtube it has no check marks for H.264 and MSE & H.264. Not sure what the problem is. Firefox does HTML 5 fine on my old laptop. I moved my profile from my old firefox to my new firefox so that I would keep all my preferences and so on. Also I am on Widnows 8.1 N if that at all makes a difference.

I think with the "N" edition you need to download the Media Feature Pack:
