Anti-Grabify от Konnor88

The Anti-Grabify add-on prevents services such as Grabify from grabbing your IP address. It currently blocks nearly 50 URLs from Grabify and other IP grabbing services. This add-on will prevent the sites from loading, which in return doesn't let Grabify grab your IP and send it to the person with malicious intent.
