Download Firefox 21 AlphaWith experimental H.264/AAC/MP3 support.

Now here is a nice update for you. It looks like just recently, Mozilla was debating whether or not to continue supporting the H.264 codec. Now, the open source organization has pushed a new batch of Firefox nightly builds that will make at least some of its users happy. Why? Well, it has enabled a support for playing H.264/AAC in MP4 and MP3 audio files in HTML5 video and audio tags by default on Windows machines.

On a side note, Mozilla has also said that we will only see H.264/AAC/MP3 support on Windows in Firefox 22, which is set for June 25 release, rather than Firefox 21.

    I think you meant “whether or not to start supporting the H.264 codec”.

  • Przemysław Lib

    Its actually support for CODECS INSTALLED ON WINDOWS. So if for some reason you do not have those codecs installed FF will not have H.264 support.

    And Moz is checking if they can do the same for GStreamer for Linux.

      install mplayer-codecs-20061022-1.i386.rpm
      and

      mplayer-codecs-extra-20061022-1.i386.rpm

      you’ll be probably good to go!

        Will it install firefox plugin for mplayer as well? Or is it just adding codecs firefox will use?
