How Does It Work?
FaceOff is a Chrome Extension that implements the 2-click "like" button, inspired by the work seen on the German tech-news site Heise.
The reason for having a "like" button instead of blocking Facebook plugins outright is respect for the content owner.
If the content owner has a "like" button, then I should be willing to share the content if I find it worth sharing.
Control Your Privacy!
The FaceOff extension blocks Facebook from tracking you by replacing the "like" button with an image.
Because the real "like" button is not loaded, Facebook can't track you.
If you want to share something with your friend, click on the image. Only then would it transform into the real "like" button.
