We designed Suggested Tiles to respect user privacy. Instead of centrally collecting as much data about as many people as possible (the strategy of all other ad-tech companies), we distribute all possible ads to all users and let Firefox decide what to show. This prevents your data "leaking", while showing you relevant advertising that you can control.

The user interface is designed to help you understand why you are seeing the ad, and to allow you to easily and permanently disable this type of advertising from your experience.

Our goal is to provide effective, relevant advertising without sacrificing user privacy.

For those interested in the transparency of this, all of the server-side software for this is on github:

And tracked openly on Bugzilla:
