I'm working on a web site with an audio player. As it is known, Firefox supports ogg format and Chrome mp3.

However, after a Firefox upgrade, now Firefox is supporting mp3, as it is playing the songs with mp3 format.

Does Firefox supports now mp3 format? If not, why is it supported just doing an upgrade?


Mozilla should pay royalties if they include a mp3 decoder in their applications. But they can circumvent that by using the decoder of the operating system and that's what they are doing with Firefox. If the operating system supports playing mp3's Firefox supports it too.


IMO, to support as many browsers as possible I would use a combination of a proprietary and an open source codec like mp3 and Ogg Vorbis.

  • Thanks. I'm using that combination and works fine. Just was surprised because of the mp3 support. – Manolo Jan 25 '14 at 15:10
