Videos in my timeline in Twitter in Firefox 41.0 won't play and give the message "This browser does not support video playback". Works ok in Google Chrome.

On Windows XP you probably do not have support for playing MP4 files in the HTML5 media player.

You can try to set this prefs to false on the about:config page.

  • media.directshow.enabled

This will disable the HTML5 media player and the website may switch to a Flash based player.

Have switched to Chrome on my XP machine, where the browser works fine, as no fix forthcoming for Firefox.
