There are numerous reasons for one to limit what others can see on your Facebook timeline. One of the items that you may want to control is who can see your friend list when they look you up or what friends your friends can see when they are on your timeline
Below are the instructions to set this security setting on your Facebook timeline.
1.) Go to your profile page
2.) Click on your friends list
3.) Click on the “Edit” button at the top Right hand corner
4.) Choose the security level you would like
a.) Public-anyone can see your friend list
b.) Friends-only your friends can see the list , but they can see the entire list
c.) Only Me-means that your friend list is hidden, except friends can see mutual friends
d.) Custom- this feature lets you choose specific people or list of people to block from seeing the list and also allows you to choose specific people who can see the list
It is that simple. Now you have control of who sees your friends list.
