Old Rang-Icons Userscript

Funktioniert bei mir bei Firefox immernoch nicht.

Folgender Text erscheint, wenn ich auf die Seite gehe:
Code:
// ==UserScript==
// @name           epvp obsolete
// @include        http://www.elitepvpers.com/forum/*
// ==/UserScript==

var images = document.getElementsByTagName("img");

for (var i = 0; i < images.length; i++) {
  var elem = images[i];

console.log('epvp_obsolete loaded');
Anscheinend ist der Code falsch.
