Firefox 37 on Ubuntu 14.10 can't use Media Source Extensions on YouTube
I saw on the release notes that Media Source Extensions was enabled for YouTube with this release. Was I mistaken?

Ah, there really should have been something in the release notes about that.

I saw that when I got the same showing on the Youtube html5 page. If you set the relevant mse flags to "true", video playback breaks (at least for some videos). Why is that?

That is the reason why it is still false on Linux. If the devs are confident that it will work then this pref will be true by default.
