Can't play videos in Twitter

Inserita

Videos on Twitter don't play, "The message This browser does not support video playback." appears on the center of a screenshot of the video. Twitter Videos play normally on Chrome. YouTube videos play normally on Firefox.

I have the latest version of Firefox and all the plugins are up to date (Java, Flash Player etc). I have experimented changing Hardware Acceleration Where Available box, the media.windows-media-foundation.enabled attribute, clearing the caches, opening in safe mode, nothing makes the videos play.


Is there anyone who has had the same problem and managed to solve it. Thank you.

Hi no1wammy, thanks for the link. For some reason, even though it's labeled as a GIF, it's actually an MP4 video embedded in a slightly different way. I revised the script to handle that alternate style of embedding.
