title: Firefox Addon SDK: Loading addon file into iframe
body: <p>I want to load a <code>resource://</code> link, respectively a local file from my Firefox addon into an <code>iframe</code> in a web page.</p>
  
  <p>The reason is, that the resource should be visually embedded into the web page while not giving the website access to it's DOM for security reasons.</p>
  
  <p>The issue has been discussed in various places in the past, e.g. here (without solution):
  <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=792479">https://bugzilla.mozilla.org/show_bug.cgi?id=792479</a></p>
  
  <p>As most of the postings are rather old, I want to ask, if in the meantime there are any new solutions or workarounds.</p>
