To use the mapper you should go to the Extensions shop, buy the extension and download it into your browser. Then you would need to restart the browser and open the FB tab right after. If you have done the installation correctly, you will be able to see the new option “reveal friends” after you go into the fellows section of the person whose audience intrigues you.
