Well, it's the latest Firefox browser version I am using. When I click the Facebook like button, the whole bordered area moves up and down for a while and than it comes the Confirm button! How strange! No content is revealed. I am already logged in my Facebook account. I am using one of the newwpthemes.com's themes. No other significant plugins are installed. Help? By the way Firebug shows that FB.GetLoginStatus is called before FB.Init. Is it related?
