Since the update this morning to FF30 i get the errormessage from the js

TypeError: Constructor XMLHttpRequest requires 'new'

Code:

function ajaxManager() { var request; var versions=new Array('MSXML2.XMLHTTP.7.0','MSXML2.XMLHTTP.6.0','MSXML2.XMLHTTP.5.0','MSXML2.XMLHTTP.4.0','MSXML2.XMLHTTP.3.0','MSXML2.XMLHTTP','Microsoft.XMLHTTP'); if(document.getElementById) { if(window.XMLHttpRequest()) { request=new XMLHttpRequest(); } if(window.ActiveXObject) { for(var i=0;i<versions.length;i++) { try{ request = new ActiveXObject(versions[i]); } catch(exception) { } } } } return request; } </p>

I hope someone know what changed or what i missed.

Chosen solution

Found a working solution now by myself:

"if(window.XMLHttpRequest()) {"

changed to

"if(window.XMLHttpRequest) {"

Seems the old way i used now not working anymore
