i have code working desktop firefox addon having difficulty 1 firefox mobile. 

function connecttoserver(awindow) {  var ws = new mozwebsocket("ws://ipaddress:8887");  // line 20 // var ws = new websocket("ws://ipaddress:8887"); ws.onopen = function() {     showtoastmsg(awindow, 'sending');     ws.send('data'); }    ws.onmessage = function (evt) {      showtoastmsg(awindow, 'display') };   ws.onclose = function() {  };

i have tried both mozwebsocket , websocket, both of them gives me error similar following :
