In a small update that might be hinting at more changes to come, Facebook has altered how users select friends to add to their friends lists. Previously, when you approved a friend request, the interface included an option to add a friend to one or more lists. Now, you just see two buttons next to each potential friend’s name: Confirm or Ignore. If you click Confirm, you’ll then see the option to add them to lists. Click on it, and a window will appear showing your existing friend lists and asking you to toggle the ones you want your new friend to be listed under.
