Signed script to do cross-domain queries
<p>I read <a href="http://developer.yahoo.com/javascript/howto-proxy.html" rel="nofollow">this article</a> which said:</p>

<blockquote>
  <p>Digitally sign your scripts. In Firefox you can apply a digital signature to your script and those scripts will then be considered "trusted" by the browser. Firefox will then let you make XMLHttpRequests to any domain</p>
</blockquote>

<p>I read <a href="http://www.mozilla.org/projects/security/components/signed-scripts.html" rel="nofollow">this page</a> to see how to accomplish this signed script, but it really didn't explain it all that well. Can someone show me how to go about signing my script?</p>
