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!
