Remove an app from Notification Center preference pane My girlfriend added Facebook to my Notification Center. I tried to set the alert style to none, and you can see the check mark to show items in Notification Center is deselected.



I want it completely gone but don't know how else to configure things.
Open Safari › Preferences › Notifications
There you can remove objects permanently by selecting the notification you wish to delete and then either hitting the delete key or by using the remove button ('-') if it exists.
