Installed -beta6, put the app ID in the settings and enabled share and like on all types (in the links position).

In firefox (firebug) I get:

b is undefined
[Break On This Error] if(!window.FB)FB={};FB.forEach=functio...B.TypeLoader.subclass,FB.TypeLoader);

on http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php line 7

In chrome I get:

Uncaught TypeError: Cannot read property '_onLoad' of undefined

on the same file/line.

Not used these fbook things before - so a little lost.
