facebook contacts does not show

Why does not the facebook contacts show on the direct messages field on the right side? Only gmail contacts. When I log on to facebook seperately in my browser I see that there is a lot of them logged in.

Because the Facebook contacts are Chat contacts so they are shown in Sidebar only.

But that is the problem. They does not show in the sidebar. Only when they log on to facebook they show for about one minute and then they go away. So I cant chat with them from emclient. Only through the facebook site.

In the sidebar only Online contacts are shown by default. Open the chat settings (by hovering over the Chat tab header) and enable showing of Offline contacts.
