I intent to unship the support of moz*Frames of HTMLVideoElement including
* HTMLVideoElement.mozParsedFrames
* HTMLVideoElement.mozDecodedFrames
* HTMLVideoElement.mozPresentedFrames
* HTMLVideoElement.mozPaintedFrames
* HTMLVideoElement.mozFrameDelay
in Bug 1379050 [1].
The reason of this is threefold.
1. They are non-standard API and Gecko is the only one implements them.
2. The VideoPlaybackQuality[2] provides a similar feature.
3. There is a potential risk of browser fingerprinting[3] for these
APIs.
For these reasons, we should remove them.
