Was it still buggy on Linux? Release notes mention some other points as relevant to the Windows version only, so it probably made sense to mention it for MSE too to avoid confusion.
Not so much buggy as less tested. I use it on my linux laptop and have relatively few issues.
Release notes have been updated to say Windows only now.
Thanks!
On a Windows 8.1 machine with FF37, I get "An error occured, please try again later." for all videos on YouTube. Disabling media.mediasource.enabled in about:config fixes the problem. Anyone else?
Do you have any addons related to video or blocking? You may need to unblock mediasource support in noscript.
