> Implemented a subset of the Media Source Extensions (MSE) API to allow native HTML5 playback on YouTube
This is great! Actually just today I was wondering why Firefox was still using the Flash player for Youtube. Now it isn't anymore :)

(Personally, whenever it fails, or sometimes even when it doesn't, I use youtube-dl.)
What am I doing "wrong"? What am I missing here?
Did you enable media.mediasource.enabled in about:config? Check it for Firefox 36, and if it's true, see if it's highlighted or not. If yes (and you are using the stock Mozilla build and not Gentoo custom one) it means you don't have the default.
Sure, you could enable it already for a while there, but it was buggy. For me the default was false. Strangely, it's false even in Firefox 37, which contradicts the release notes. But at least it works well now in actual videos when enabled.
As you can see, media.mediasource.enabled is disabled by default.
There's a few plugins (eg: youtube-center) that let you play any video via the HTML5 player.
Personally, I got rid of flash sometime around 2011. The only side effect is firefox not crashing ever.
As a bonus, I noticed that a few months ago youtube added video ads that you can't skip to lots of videos (noticed it on my gf's iPad). You'll never have to deal with those with the HTML5 player (or maybe it's just adblock).
It does work if I disable Flash in the browser, but if it is enabled the videos are always played via the Flash plugin.
Is there some setting I have to turn on/off?
Firefox 37 seems to have fixed this issue for me.
