We all love privacy and you will definitely need lots of that if you use facebook for more personal reasons than just socializing. You can hide your facebook friends list and even new friends you make. This makes the list invisible to your friends and everybody else except you. To hide your facebook friends list from your profile, go to your profile page and follow these steps:
How To Hide Friends List From Profile
-Locate the friends list on the left side bar
How To Hide New Friends From Profile News Feed
Now, if you need to hide new friends from showing on your wall too, here’s what to do:
-Go to your profile and locate a friending activity and click on the remove button (X) next to it.
-Select Hide All Recent Friending Activity From Profile
This hides new friends from showing on your wall. In addition, there’s a detailed post here on how to control your wall news feed including new friends and how to hide other recent activities.
