In Firefox, you cannot request other websites (websites that do not use relative path, like http://www.google.com) on client side.

I got the same issue, but with Firefox 12. I use this code to call my COMET server:


           function getXmlHttpRequestObject() {
               if (window.XMLHttpRequest) {
                   //document.getElementById("_receivedMsgLabel").innerHTML += "Non-microsoft xmlHttpRequest object created.
"; alert("Non-microsoft xmlHttpRequest object created."); return new XMLHttpRequest(); } else if (window.ActiveXObject) { //document.getElementById("_receivedMsgLabel").innerHTML += "Microsoft xmlHttpRequest object created.
"; alert("Microsoft xmlHttpRequest object created."); return new ActiveXObject("Microsoft.XMLHTTP"); } else { alert("Status: Could not create XmlHttpRequest Object. Consider upgrading your browser."); //document.getElementById("_receivedMsgLabel").innerHTML += "Status: Could not create XmlHttpRequest Object. Consider upgrading your browser.
"; } }
           var sendReq = getXmlHttpRequestObject();
           var receiveReq = getXmlHttpRequestObject();
           var lastMessage;
           var mTimer;
           //Gets the server response:
           function getResponse() {
               document.getElementById("_receivedMsgLabel").innerHTML += "getResponse() called.
"; if (receiveReq.readyState == 4 || receiveReq.readyState == 0) { //if (receiveReq.readyState == 0) { //receiveReq.open("POST", 'http://tardis:1802', true, "server", "server123"); //receiveReq.open("POST", 'http://localhost:1802', true, "server", "server123"); //receiveReq.open("POST", 'http://holit109:1802', true, "server", "server123"); //receiveReq.open("POST", "http://localhost:1802", true, "server", "server123"); receiveReq.open("POST", "http://L45723:1802", true, "server", "server123"); //must use this URL at work. receiveReq.onreadystatechange = handleReceiveMessage; alert("handleReceiveMessage assigned to onreadystatechange event."); receiveReq.setRequestHeader("Content-Type", "text/x-json"); receiveReq.timeout = 0; var currentDate = new Date(); var sendMessage = JSON.stringify({ SendTimestamp: currentDate, Message: "Message 1", Browser: navigator.appName }); //receiveReq.send("<Request><Command>Queue</Command><User>user1</User><Message>Message 1</Message><Message>Message 2</Message><Message>Message 3</Message></Request>"); alert("JSON message created. About to send..."); receiveReq.send(sendMessage); alert("Message sent.");
               }
           }
           //function for handling the return message from Comet
           function handleReceiveMessage() {
               if (receiveReq.readyState == 4) {
                   document.getElementById("_receivedMsgLabel").innerHTML += "Message received!
"; var status = receiveReq.status; //document.getElementById("_receivedMsgLabel").innerHTML += "Status received!
"; var txt = receiveReq.responseText; var receivedMsg = JSON.parse(txt); document.getElementById("_receivedMsgLabel").innerHTML += receivedMsg.Message + "
"; //var receivedTime = new Date(); //alert("Got current date."); //alert(receivedTime); //var receivedTime_ms = receivedTime.getTime(); //alert("Got time message received in ms."); //alert(receiveReq.SendTimestamp); //var sentTime_ms = getDateFromFormat(receiveReq.SendTimestamp, "dd/MM/yyyy HH:mm:ss"); //var sentTime = new Date(receiveReq.SendTimestamp); //alert("Got time message sent in ms."); //var sentTime_ms = sentTime.getTime(); //var difference_ms = receivedTime_ms - sentTime_ms; //document.getElementById("_receivedMsgLabel").innerHTML += "Comet took " + difference_ms + " ms.
";
                   mTimer = setTimeout("getResponse();", 0);
               }
               getResponse();
           }

The handleReceiveMessage() event handler is called, but there is no data returned in the responseText property of the xmlHttpRequest object.

Why?

This works fine in IE9.
