This will only disable webm VP8 + VP9, forcing FF to fallback to H264.

In order to enable MSE & WebM VP9 in Firefox nightly, you must leave:

media.webm.enabled=true (default)

media.mediasource.enabled=true (default)

The only value you must change is:

media.mediasource.webm.enabled=true (user-set)

I'm glad you edited your comment but I'm still not sure what you disagree about. SoapSeller was talking about hardware acceleration and in that context disabling WebM globally will provide better performance/battery-life.

The only thing I was contributing to the discussion was the note that on Firefox this does not require an extension.
