Hi,
this started happening today (or recently) with any video from Facebook:

On the very day my Flash plugin started being blocked by Firefox. ;-)

You are using an outdated version of youtube-dl. Since Facebook changed their interface on December 9th, you'll need at least youtube-dl 2014.12.10.3 to download all Facebook videos. See our FAQ if you have trouble updating.
