Same problem here. Tried repeatedly to add Facebook account but failed because there was no "Add" button after completing authorisation. (Didn't realise there was supposed to be one until I read this!). Facebook accepted Gwibber as an authorised application, so no problem that side. Was finally successful after using Facebook username to authorise rather than my sign in email address. Thanks Marcos (post #9)
