Body is undefined

I have the following code in javascript (firefox extension)

var body;

var Test = {
initializeBody: function(e) {
  if (!e.originalTarget.defaultView.frameElement) {
    body = e.target.ownerDocument.getElementsByTagName('body')[0].cloneNode(true);
  }
}
}

window.addEventListener("DOMContentLoaded", function(e) { Test.initializeBody(e); }, false);

when I want to use body variable in another function Error console writes that body is undefined . I understand that not all firefox pages have body tag defined, but it writes this message even if I load http://www.google.com

Do you know what is wrong?

thank you

If body is undefined, I'd assume that nothing was assigned to it, probably because !e.originalTarget.defaultView.frameElement expression evaluates to false. What's that condition for?

you need to use document.body for accessing the body tag of a document
