Hi,
F22, latest Firefox 40. With standard configuration, I can't play any highres video on Youtube (720 or 1080p). When setting
media.mediasource.enabled media.mediasource.webm.enabled
to "true" as recommended by the Mozilla Community, highres videos play just fine. BUT some other videos now do not play any longer. In particular, when setting
media.mediasource.webm.enabled
to "false", those non-working videos work again. But then, no highres is possible. Example:

WTF?!
