Comment (by cohosh):

 Here's a look at the PeerConnection configuration in Firefox:
 {{{
 {…}
   bundlePolicy: "balanced"
   iceServers: (1) […]
     0: {…}
       credentialType: "password"
       urls: Array [ "stun:stun.l.google.com" ]
       <prototype>: Object { … }
     length: 1
     <prototype>: Array []
   iceTransportPolicy: "all"
   peerIdentity: null
   <prototype>: Object { … }
 }}}

 The difference here between Firefox and Chrome is that Chrome sets the
 credentialType field to the empty string `""`. `credentialType` should
 only be set for a TURN server. It seems that Firefox sets this field to
 `password` by default, it's possible this is causing problems with the
 STUN server, but setting `credentialType: ""` gives an error.
