Notes

WebVTT must be used with the <track> element.

Firefox currently lacks support for the ::cue pseudo-element. See bug #865395.

In Firefox, captions are not visible for audio-only files in the video tag (see bug).
Firefox 46 and below do not support the textTrack.onCueChange() event (see details).
