An ad-tracking extension for Chrome and Firefox

MyAdPrice allows you to track how much money advertisers bid to show you ads as you surf the Web. It utilizes hooks in the Prebid library along with other methods to track this activity. By default, it sends out no data from the user's device. However, users can opt-in to send specific, anonymized statistics to our servers to help in our research.

This extension has been developed by researchers at Duke University, Max Planck Institute for Informatics, University of Illinois at Urbana-Champaign, and ETH Z├╝rich. We have made the extension source code available here, and our collected dataset can be downloaded here.
