I've searched high and low for this and can easily reproduce it. Running absolute latest PHP SDK and the JS is coming directly from facebook over an HTTPS connection. My 'MyAppId' and domain have been changed in the code that follows. Substitute your own to reproduce.
This is with Firefox 8 and Firebug.
Code to reproduce: `
<body>
<div id="fb-root"></div>
<script type="text/javascript">
window.fbAsyncInit = function() {
FB.init({
appId: 'MyAppID',
status: true,
oauth : true,
cookie: true,
channelURL : 'https://www.mydomain.com/channel.html'
});
FB.Canvas.setAutoResize();
FB.Canvas.scrollTo(0,0);
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
Test
</body>
</html>
`
It is most definitely the calls to FB.Canvas that are generating the error. If I comment both out, no error. If I uncomment one or the other or both - Error.
The code was working fine until a few days ago. Targeting the top of the page and scaling the iframe properly. I believe this is a FB JS error.

It seems like a bug of FireBug :)
steps of reproducing: http://code.google.com/p/fbug/issues/detail?id=4991

discussed: http://groups.google.com/group/firebug/browse_thread/thread/2517d5f867b9f526/90f066856b45786f
so take it easy :)

The problem is not the ff or the fb plugin is the firebug. I checked A page with ff 8.0 and firebug 1.84 and got the error. Then I checked ff 8.0 with firebug 1.8.3.
This is the compatibility table: Firefox 3.6 with Firebug 1.7.3
Firefox 4.0 with Firebug 1.7.3
Firefox 5.0 with Firebug 1.8.2 (and also Firebug 1.7.3)
Firefox 6.0 with Firebug 1.8.2 (and also Firebug 1.9 alpha)
Firefox 7.0 with Firebug 1.8.2 (and also Firebug 1.9 alpha)
Firefox 8.0 with Firebug 1.8.3 (and also Firebug 1.9 alpha)
Firefox 9.0 with Firebug 1.8.4 (and also Firebug 1.9 alpha)
Firefox 10.0 with Firebug 1.9 alpha
So... don't worry be happy. Is not a real error... I think. :P
