Extension [exclusive] — Facebook Friend Mapper Chrome

Click "Start Mapping." Warning: If you have 1,000+ friends, this can take 2-5 minutes and will consume significant CPU power.

If you are on a "digital declutter" mission, the mapper helps you identify "orphan nodes"—friends who have zero mutual connections with anyone else on your list. These are often old acquaintances, spam accounts, or people you met once at a conference. If they don't connect to your core social graph, you might decide to unfriend them. facebook friend mapper chrome extension
