Hi
I try to call a XPCOM-Interface function:
var iface = Components.interfaces.nsIMessenger var inst = Components.classes["@mozilla.org/messenger;1"].getService(iface); inst.OpenURL("http://www.google.com");
I don't believe the messenger is a service, replace getService with createInstance and see if that helps.
You also don't mention if you're trying to run this from the browser or within something like XPCShell.
