title: Basic method to Add html content to the page with Greasemonkey?
body: <p>Is there a Greasemonkey method to append basic HTML content to the end of a page right after the <code>&lt;body&gt;</code> tag, or right before it ends?</p>
  
  <p>I found before/after methods but I need to know names of elements which may change page to page.. </p>
