Why am I getting Facebook push notifications even though I have all Facebook push notifications disabled?
The answer Matthew Frederick gave should do the trick, but if you want to disable them from within the Facebook app itself, the alternative approach is to:


Open the Facebook app
Press the ≡ button in the upper left and scroll down to Settings
Select Account Settings
Select Facebook Notifications
Select Push Notifications
Uncheck any of the four boxes there


Close Friends List Activity
Group Posts and Comments
Tags You in a Post
Mentions You in a Comment



If you are receiving additional notifications, they may be coming from the Facebook Messenger app which is separate from the main Facebook app and I believe has it's own settings for push notifications relating to private messages.
