title: iFrame in a Safari Extension "Popover"
body: <p>I have a Chrome and Firefox extension, and I am making the same one for Safari. </p>
  
  <p>These plugins all have a popup. In other words, an icon you click on and a page opens up. My Chrome extension popup opens an HTML page in te plugin folder with an iFrame. The FF extension links directly to the PHP page on the server for the popup.</p>
  
  <p>I need to do with Safari what I have done with Chrome. I need to make a local HTML page which has an iFrame to the page on the server. This works in chrome, but the iFrame in Safari is just blank.</p>
  
  <p>Thanks for any help...</p>
