Using 5.0.6-beta3 and the Send to XBMC/Kodi Firefox addon, the Youtube addon seems to load the WebM version of the video, which has no playable video on the Raspberry Pi. The old Youtube addon mitigated this issue by allowing me to select which quality video (fmt code) to load before playing the video.
EDIT: Commenting out all WebM related definitions per constrainer's suggestion gives the error ' Exception: unknown format for itag "43" '
