title: Elevating a browsers javascript permission?
body: <p>I'm working on an internal tool, and I recall there being some way to make your script prompt for elevated permissions, and if accepted, allowing cross site requests etc...As this is an internal tool, this may accomplish something I need.</p>
  
  <p>Does anyone know how to do this?</p>
  
  <p>To elaborate, I'm actually trying to read (in javascript) the contents of 3rd party tracking iframes injected into our page, to give some performance analytic information. These iframes are obviously from a different domain. If I were to proxy them, they would no longer give accurate information, so that option is out.</p>
