Can not play MP3 files
Hey guys. I am pretty new to Firefox. I used to brows on Google Chrome before. And i decided to make a switch to Firefox.
I have now spent maybe a month and i feel finaly at home with it. Although now when i had to play different files online i stumbled on this problem i've never had before.
I can't play any of the files mentioned in the Title.
When i try to play a MP4 video i get this Error: " "Video format or MIME type is not supported "
And when i try to play a MP3 i get this Error: "The file couldnt be playd because it is broken" Also in the Console Window i get this error: ".mp3 Couldnt be decoded."
Example on sites that i can't play this files are these
Mp4: http://playrust.com/friday-devblog-16/ mp3: http://soundcloud.com
I have Windows 8.1 if that is interesting too.
Chosen solution
Unlike Chrome, Firefox depends on some components of Windows (Media Foundation) to decode MP3 and MP4 media. Apparently some versions of Windows 8.1 do not include all of the media features. I have no idea whehter your is one of those, but Microsoft has a download page where you can get those feature if that is the issue:
- Media Feature Pack for N and KN versions of Windows 8.1 http://www.microsoft.com/en-us/download/details.aspx?id=40744
Edit: According to a blog post I read, Microsoft was forced to unbundle these features and provide the separate download due to antitrust concerns in Europe, so this may be a more common problem than I had realized.

That actually solved the problem! Thank you so much!
I had no clue that MS was forced to unbundled those features. If that's the case then this might be a big problem for Firefox all over Europe.
I mean my friend and i have lurked around on the Internet trying to find solutions to the problem but couldn't find any. And we are actually pretty technical and still we didn't know all this.
Once again thank you!
Thank you for reporting back. I just learned about it this afternoon. We should add it to the help article here if it isn't already in there.
Note that there is a newer version.
