Disable JavaScript Alerts GeckoFX C#

Question

I'm trying to disable JavaScript alert in GeckoFX-33 + xulrunner 33 ( winforms c# ) but I can't find a solution. I check the example codes, source code but I just can't find something that blocks the alert out. I searched in about:config as well without success.

Anybody knows where I could find a reference at last ?

      geckoWebBrowser1.JavascriptError += (sender, error) =>
        {
            GeckoWebBrowser browser = geckoWebBrowser1;
            string text = "window.alert = function(){};";
            using (AutoJSContext context = new AutoJSContext(browser.Window.JSContext))
            {
                string result;
                //toolStripLabel1.Text = "was is loaded?";

                context.EvaluateScript(text, (nsISupports)browser.Window.DomWindow, out result);
            }
        };

Here is the final code for Gecko 29.
