Firefox Implementation Details

getUserMedia, PeerConnection and DataChannels are implemented in the desktop version of Firefox for Windows, Linux and Mac. getUserMedia does not require any flags to use in Firefox 20 or later. PeerConnection and DataChannels do not require a flag for Firefox Nightly versions after February 19, 2013.

We don’t have TURN support yet, but we plan to support it soon.


We support the Opus audio codec as our preferred audio codec. We also support G.711 for compatibility with devices that have not yet implemented Opus.

Recording API

We have not implemented the Recording API yet, but we plan to support it in future versions of Firefox.
