Since many years, Mozilla has given up its last gasp, since year after year the company has presented countless plans to not only generate the necessary financial resources, but also to keep the company afloat.
With the arrival of Laura Chambers as CEO of Mozilla, Many positive changes were speculated and improvements that could provide different paths for Mozilla.
And now it seems that one of them could be the solution to Mozilla's financial problems, as the company has decided enter the advertising market with a platform focused on privacy.
With Mark Surman, from the Mozilla Foundation, They announced that they will use technology from the startup Anonym, recently acquired, to build this advertising network. Mozilla's approach will be to balance the advertising model, which has traditionally compromised user privacy, with principles of openness and data control.
We have the first steps toward a theory of how to fix this: a combination of different business practices, technology, products, and public policy commitments. And we have begun to work on all of these fronts.
Mozilla's plans include the development of new infrastructure for online advertising, which, through the use of cryptography and differential privacy techniques, will demonstrate that it is possible to support businesses without revealing personal data.

Anonym, whose technology will serve as the basis for Mozilla's advertising platform, was Founded in 2022 by two former vice presidents of MetaThese founders are looking to implement a secure environment for storing data using encryption, so that advertisers and advertising platforms do not have access to individual user information. This technology is expected to enable efficiency analysis and evaluate the results of advertising campaigns based on anonymized data.
To achieve this on its platform, Mozilla proposes the following guidelines:
- Regulation: Promote consumer privacy and competition through policies that strengthen user control over their data, working with legislators and regulatory authorities.
- Standards: Actively participate in the creation of privacy-respecting technical standards for advertising, working on initiatives such as Interoperable Private Attribution (IPA) and contributing to the Private Advertising Technology Community Group (PATCG).
- Products: Develop concrete solutions to support non-invasive advertising, using tools such as Total Cookie Protection and Enhanced Tracking Protection, and working with Anonym to establish a model to demonstrate how advertising can be sustainable without compromising user privacy.
To prevent tracking of individual users, the platform Anonym will employ differential privacy methods, that They allow precise statistical operations to be performed on encrypted data sets without the need to decrypt them. or identify individual records.
It's become clear to us over the past few weeks that what we haven't done is step back to explain our thinking in the broader context of our advertising initiatives. For that, we owe our community an apology for not engaging and communicating our vision effectively. Mozilla is only Mozilla if we share our thinking, engage people along the way, and incorporate that feedback into our efforts to help reshape the ecosystem.
For instance, The platform will be able to analyze the intersections of data sets in a generalized way, orUsing encrypted statistics about ad impressions and advertiser purchase data. In this way, Advertisers will be able to know the number of users who saw your ad and made online purchases, without being able to identify to those specific users within the total number of buyers.
It is worth mentioning that the proposal Mozilla's focus is on create a system that allows advertisers to operate without having to access users' personal data, using techniques such as cryptography and differential privacy to keep information secure and anonymous. This is presented as a solution to the problem of data collection, which has been criticized in the current advertising model.
Furthermore, Mozilla is committed to maintaining transparent communication with the community about its intentions and developments, especially following the controversy sparked by the implementation of the Privacy Preserving Attribution (PPA) feature in Firefox, which had not been properly communicated prior to its introduction.
