Facebook said Tuesday it will start telling users which websites track them across the web — and offer them the option to delete the personal data from their accounts.

The social media site collects information on Facebook users and non-Facebook users from third party websites that use Facebook's services, like the "Like" plug-in or Facebook "pixels," which are pieces of code that track what people do off of Facebook.
