Before last week’s update, the company had the ability to watch what sort of content you interact with the most on Facebook. It would then serve you ads across the internet according to those preferences without giving the user the ability to turn the tracking off.
Here’s how to opt out of ads in the new setting:
Step 1: Click the lock in the top-right corner of your Facebook profile, and select “See More Settings” at the bottom.
Step 2: On the left-hand side, select “Ads.”
Step 3: Next to the “Ads on apps and websites off of the Facebook Companies,” click “Edit.” Then set this option to “No.”
