Hmm, I wonder if there were any Media Source Extensions improvements.

Not sure but Youtube videos still only play in 360p without Flash

Huh? I get 360p and 720p without flash. 1080p and 480p are still missing without MSE though.

720p should also be an option by default.
If you enable MSE from about:config, you can get all resolution types (and it works pretty flawlessly)

http://www.youtube.com/html5 can get 4K without Flash.
