FB is not defined in Firefox 4 but works on lower Firefox versions, Internet Explorer, Chrome, Safari. I've tried async loading and the following solutions mentioned here

FB is not defined error in Firefox 4

How to workaround 'FB is not defined'?

I've also removed extensions that could trigger this such as AdBlock.

Anybody here experienced the same thing? I don't know what I could've missed... oh boy...

Also, I am experiencing many errors in Firefox 4 when I visit other websites... makes me wonder if the FB is not defined error is a Firefox bug or something...

Man!

I'd really appreciate any opinions or suggestions... Thanks!

It may not be the exact same problem but one thing that worked for me was to move the FB include right to the top of the head element.

<head>
    <script src="http://connect.facebook.net/en_US/all.js" language="Javascript" type="text/javascript"></script>
