title: Greasmonkey persistent Iframe or overlay across many pages within a single website
body: <p>I have a script for Greasemonkey and I have managed to add a element to a page that's sort of easy but I would like to add a persistent frame so that each time I move between pages on the website like /page1.php /page2.php etc the frame wont be refreshed.</p>
  
  <p>Has anyone got a suggestion for a way to do this?</p>
