Unsubscribe from all Amazon Birthday Alerts

gistfile1.js

/*

At some point I connected Facebook friends to Amazon wishlists. Now I get 
multiple emails from Amazon for the birthday of everyone I ever met.

Removing people from this list requires a bunch of manual clicking.

Automation FTW.

1) http://www.amazon.com/gp/registry?ie=UTF8&type=wishlist
2) Paste this into Console
3) Make a coffee
