  };

  var container = document.getElementsByTagName('iframe')[0].contentWindow;
  var frames = container.document.getElementsByTagName('iframe');

  for (var i = 0; i < frames.length; i++) {
    uncrippleFrame.call(frames[i]);
    frames[i].onload = uncrippleFrame;
  }
})();

works great as of today. I'm going to make this a glimmerblocker plugin so it just always runs =)

i'm pretty new at this. downloaded the file, but can't get it to open in any of my browsers (tried IE and firefox). any suggestions?

Just tried it with Safari 5.1.4 on my Mac and it doesn't work at all. No errors in the dev console either.
