Notification centre in Lion and Facebook When notifications pop up from the notification centre for Facebook posts nothing happens when I click the show button.

If a tweet comes along the show button opens up a browser tab.

Any ideas why this isn't working for Facebook and is working for Twitter?
OK, go to your Facebook 

open your settings and go to the the Notifications

Make sure the app request and activity for OSX is checked

In Notification on your Mac click on the facebook and a window should open where you can post directly to facebook from your mac.
