error Component returned failure code: 0x80040111

[danteq]

Hola a todos

Tengo un ajax que estaba funcionando bien pero de repente empezo arrojarme errores en mozilla del tipo Component returned failure code: 0x80040111 en la parte del envio de datos POST y no se como solucionarlo.

Este es mi codigo

Código:

Request = function(){
	var Request = window.XMLHttpRequest?new XMLHttpRequest():window.ActiveXObject?new ActiveXObject("Microsoft.XMLHTTP"):false;
	
	Request.fn = function(fn){
		if(typeof fn=='string')return new Function(fn);
		if(typeof fn=='function')return fn;
		if(typeof fn=='undefined')return new Function();
	};

	Request.config = {
		'xml' : false,
		'404' : 'File not found'
	};

	Request.success = false;
	Request.loading = false;
	Request.error = false;

	Request.submit = function(obj){
		if(Request){
			Request.onreadystatechange = function(){
				if(Request.status==200){
					if(Request.readyState==4){
						Response = Request.config['xml']?Request.responseXml:Request.responseText;
						if(Request.success){
							Request.fn(Request.success).call(this, Response, Request);
						} else {
							Request.fn(obj.success).call(this, Response, Request);
						}
					} else {
						if(Request.success){
							Request.fn(Request.loading).call(this, Request);
						} else {
							Request.fn(obj.loading).call(this, Request);
						}
					}
				} else {
					if(Request.success){
						Request.fn(Request.error).call(this, Request.config['404']);
					} else {
						Request.fn(obj.error).call(this, Request.config['404']);
					}
				};
			}

			Request.open("POST", obj.url, true);
			Request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=utf-8'); //esto es para el error 406 de los servidores
			//Request.setRequestHeader("Connection", "close");
			Request.send(null);

		} else obj.error.call(this, Request);
	};
	return Request;
};
