Grok's Mass Unfriend JS - When you open your Friends List, you will notice three buttons: Start Analyzing, Unfriend all Friends, and Stop Analyzing. Navigate through each page while analyzing so it adds to the list, then, once you're finished, stop analyzing. It will then prompt each friend detected to unfriend them. Don't worry about clutter! It only has a 5-tab limit and closes after unfriending. Enjoy!
