title: javascript not running. Firebug says "reload the page to get source for: ..."
body: <p>I am trying to develop a bookmarklet which add some javascript elements to head of webpage. But I noticed that one of them is not loading.

  <p>Is there is some way to overcome this problem. Is it possible to reload page without loosing appended scripts?</p>
