I'm using FF 43.0.1 on Windows.

Before I upgraded, videos played without any problem.

Now, when trying to play the top video on this page https://twitter.com/TwitterTips/timelines/581843572464443392 , 

I get the message "This browser does not support video playback."

What's gone wrong ?

How do I resolve the issue, please ?

You are probably out of luck with being on Windows XP. XP doesn't support playing MP4 files natively, so Firefox isn't able to play MP4 files via the HTML5 media player.
