Powering the evolution of performance and privacy

Contact

Mozilla is redefining digital advertising with privacy-first, high-performance solutions.

Pushing the industry forward with advanced technology, for a better + safer internet.

Today’s digital advertising practices put personal data at risk, tracking people across websites without their knowledge or consent.

Mozilla is leading the charge, creating innovative solutions that deliver ad performance while safeguarding privacy. Our approach creates resilience for advertisers and publishers against continuous changes, and privacy protection to consumers.

Performance, driven by privacy

Anonym enables brands to optimize and measure their advertising without sharing user-level data with ad platforms.

We’re building an ecosystem that provides consumer privacy, where data-driven marketing thrives.
