What does 'media.windows-media-foundation.enabled' do?

I disabled media.windows-media-foundation.enabled in order to get .mp3/mp4 to stop playing in firefox, but rather prompt me to open/save as. It works fine. However, the place where I found this solution said it was going to break some embedded playback functionality.. or something.

Vimeo still works, HTML5 Youtube still works, Vine still works. I'm not sure what is supposed to break, and I *KNOW* I'm going to find it eventually and completely forget that I ever did this. Can anyone explain what is supposed to stop working?

Thanks! :)

It disables/or enables Firefox's internal media player.

It should disable most HTML5 audio/video too.

That's what I was told originally, but like I said most HTML 5 video continues to play. Do you have an example that shouldn't work?

Media Foundation is used to decode MPEG media, such as MP3 and MP4. Many sites that feature HTML5 are using alternative formats such as WebM that are not patented.

I think you might occasionally have a problem on some sites. For example, the site might only offer MPEG media in its HTML5 player and use a script that doesn't test carefully and provide an alternative (e.g., Flash player media) for browsers that do not support MPEG media. But... hopefully not too many sites.
