While Facebook's new advertising setup allows you more control over how they use your data, it also allows Facebook to collect more of your data. While you can limit your digital habits and some settings, your data and history are still being cached and shared. To keep your browsing history safe from Facebook's advertisers, you have to actively opt-out.
Here's how to do that.
Note: In order to do this, please turn off AdBlock Plus or any other program you may be running that disables cookies. If you clear your cookies regularly, you will need to repeat the opt-out process, every time you do so.
