Hi friends, you must have seen that facebook gives you different option to control your privacy settings, on your statuses, posts and even on friend list. If a friend has made their friend-list hidden (visibility set to "Only Me") then you can't check their friends, as I've done. But now, a new Free Chrome extension "Facebook Friends Mapper" can reveal all friends of such users.
How to use Facebook Friends Mapper Chrome extension?
1. Install Facebook Friends Mapper extension from Chrome web store.
2. Open Facebook Profile of user you want to target.
3. You will find 'Reveal Friends' option on Friends tab.
4. Click on Reveal Friends and Bang!
Note: There must be at least one mutual friend of the user of which you want to reveal friend list, no matter victim is in your friend list or not.
