Add a Friend Without Knowing Their Name with Facebook's Updated Find Friends Browser

Facebook has changed the interface for its Find Friends Browser, switching to checkboxes for filtering, adding infinite scroll, and making the Add as Friend buttons constantly visible. The friend suggestion tool has been refocused to help you find other users that share profile traits with your friends, not just you. For instance you’ll see filters for hometowns or employers you’ve never listed, but which many friends have. This update makes it easier to find someone you’ve met through your friends, such as when visiting their hometown or company headquarters, even if you don’t know their name.
