Mozilla has teamed up with non-profit The Markup, and the pair are recruiting for the Facebook Pixel Hunt study, asking users to download Rally – Mozilla’s privacy-first data-sharing platform, launched last year – and share their own browsing behaviour. Mozilla Rally is an opt-in data contribution platform that shines transparency on Big Tech.
Tools provided by Rally allow monitoring of the Facebook pixel, a piece of Javascript that tracks the actions of users in response to ads. They should allow the companies to examine what data is collected, which sites it’s shared with, what data it reveals about users and how widespread Facebookâs tracking network actually is.
