Facebook gives you an array of customizable privacy settings. Your friends list, by default, can be viewed by other Facebook users. If you don't want everyone to see your list, you can adjust your settings. Change your settings to hide your list from everyone, or create a list of friends to hide it from. To access your privacy settings, you'll need to sign in to your account on your computer rather than on a mobile device.
