And I am talking about Media Source Extensions, MSE H.264 and MSE & WebM VP9 not being supported.

Hello, this limits quality settings. Only 360p and 720p are available.

Apparently MSE (note that all three unavailable things are MSE) is not implemented well enough yet even on Windows where they tried to enable it by default: bug 1129039.

If you want to try helping, you could try out the Nightly build of Firefox. 
Other than resolutions over 1080p, my HTML5 playback is flawless now.
