I have downloaded the file to local system but the error is still there. i get the error from init function in RTCMulitiConnect.js. (while debugging the error is throws at line 4107 RTCMulitiConnect.js)

Please make sure that you are NOT using adapter.js or similar solutions.

Open Chrome Console (ctrl+shift+i or command+option+i) and type RTCPeerConnection. Chrome console MUST throw error because RTCPeerConnection is hidden object. If it shows some kind of function then either remove adapter.js or modify RTCMultiConnection.js as following:

var RTCPeerConnection = window.mozRTCPeerConnection || window.webkitRTCPeerConnection;
var RTCSessionDescription = window.RTCSessionDescription || window.mozRTCSessionDescription;
var RTCIceCandidate = window.RTCIceCandidate || window.mozRTCIceCandidate;

If you'll keep using adapter.js then RTCMultiConnection MAY-NOT work in latest Firefox releases. (where mozRTCPeerConnection is expected to be removed, soon)
