Hello, this has nothing to do with the update. TenFourFox has never been able to play mp4 videos natively. It may be able to do so in the future. For now, you can play web.m videos, e.g. most (if not all) Youtube videos. However, you can always play mp4 videos locally with QuickTime Player once they're downloaded to your HD.
If you *know* you were able to play a specific video before and cannot anymore after the update, please give me a URL with the video so I can have a look at the problem.

Well it doesn't matter which url it is. Best example is streamcloud.com
I just can't push the play button. The browser always wants me to download
the video immediately.
