title: Unsafe JavaScript attempt to access frame warning in Safari
body: <p>I'm using Facebook Connect in my app. I have it working pretty well, but in the Safari Error console, I'm seeing errors like this:</p>
  
  <pre><code>Unsafe JavaScript attempt to access frame with URL http://...#... from frame with URL http://www.connect.facebook.com/extern/login_status.phpapi_key=..&amp;extern=2&amp;channel=http...xd_receiver.htm.
  Domains, protocols and ports must match.
  </code></pre>
  
  <p>The app seems to function ok, though we are seeing periodic hangs and other bad behavior from Safari. When I run other Facebook Connect apps, I sometimes see this error too, so I don't think this is a problem with our implementation. Is it safe to ignore this warning?</p>
