ajax.status not working with firefox 6 - always returns status 0. This feature is basic, was working with firefox 5. What have you done and how can I make my website work again with ajax?

more options

I am developing websites using ajax. With firefox 6 ajax.status is only returning 0 not 200. I have not changed my code. It works with earlier versions of Firefox and with Chrome 13. I have defined a javascript variable ajax1 at beginning of program, typical procedure.

function ajaxFunction(){ var ajaxRequest; // The variable that makes Ajax possible!

 if (window.XMLHttpRequest) {
  // IE 7, Mozilla, Safari, Firefox, Opera, most browsers:

ajaxRequest = new XMLHttpRequest();

  } else if (window.ActiveXObject) { // Older IE browsers
   	// Create type Msxml2.XMLHTTP, if possible:

try { ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e1) { // Create the older type instead: try { ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e2) { } } } // Send an alert if the object wasn't created. if (!ajaxRequest) { alert ('Some page functionality is unavailable.'); } else {

return ajaxRequest;
}

var ajax1 = ajaxFunction(); var ajax2 = ajaxFunction();

This code below does not not work because firefox 6.02 is not returning anything but 0 for the status: if (ajax1.readyState == 4) && (ajax1.status == 200){

You have done something with your javascript engine that is causing this problem. How can I get ajax to work using post method - am using code like this which WAS working in earlier versions of firefox:

var post_data = 'email=' + encodeURIComponent(email);              
    ajax1.open('post', 'check_4_company.php',true);
    ajax1.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    ajax1.onreadystatechange = handle_mope;
    ajax1.send(post_data);
    return false;

This code is very basic, have used it hundreds if not thousands of times successfully!

But firefox 6 has messed things up!

Please advise!
