Could you share the link of the tweet with the video, please.
That said, https://video.twimg.com/tweet_video/DBTruj_WsAAp_IH.mp4 works for me in Nightly on Win 7.

It looks as though whatever was causing this bug has been fixed in today's Nightly release. I'll reopen this if I can reproduce it again.

The error was 404. It's a twitter issue, nothing to do with firefox.
