I haven’t looked into the technicals much further than the support page.
The way i read it, it sounds like the companies will get some general data if their ads work without a profile about you being created. I would be fine with that. What I don’t like is the lack of communication to users about it being enabled.
PPA does not involve websites tracking you. Instead, your browser is in control. This means strong privacy safeguards, including the option to not participate.
Privacy-preserving attribution works as follows:
- Websites that show you ads can ask Firefox to remember these ads. When this happens, Firefox stores an “impression” which contains a little bit of information about the ad, including a destination website.
- If you visit the destination website and do something that the website considers to be important enough to count (a “conversion”), that website can ask Firefox to generate a report. The destination website specifies what ads it is interested in.
- Firefox creates a report based on what the website asks, but does not give the result to the website. Instead, Firefox encrypts the report and anonymously submits it using the Distributed Aggregation Protocol (DAP) to an “aggregation service”.
- Your results are combined with many similar reports by the aggregation service. The destination website periodically receives a summary of the reports. The summary includes noise that provides differential privacy.
This approach has a lot of advantages over legacy attribution methods, which involve many companies learning a lot about what you do online.
PPA does not involve sending information about your browsing activities to anyone. This includes Mozilla and our DAP partner (ISRG). Advertisers only receive aggregate information that answers basic questions about the effectiveness of their advertising.
This all gets very technical, but we have additional reading for anyone interested in the details about how this works, like our announcement from February 2022 and this technical explainer.
My question is why Mozilla is trying to help advertisers at all instead of telling them to fuck off.
Telling advertisers to fuck off works if your goal is to create a niche product tailored to people who care deeply about privacy already. But Mozilla is very much all about trying to make things better for everyone on the internet, regardless about their opinions (or lack thereof) on privacy and ads.
Mozilla has recognised that advertising isn’t going anywhere, so there’s two options:
- Reject ads wholesale and become irrelevant.
- Push for a better alternative that can improve privacy while still keeping the engine that drives the internet intact.
What other major player would ever push for privacy preserving attribution? Hint: no one. While I get that many people here want 0 ads (myself included), PPA is a great step in the right direction, and could have a huge positive impact if it’s shown to work and other companies start adopting it.
And guess what? You can still turn it off, or use adblockers. Unlike Chrome, Firefox won’t restrict you in that regard.
Firefox has a long history of marketing itself as privacy-focused. This was not about privacy. This was not about “making things better for people on the Internet,” it was about a few individuals enriching themselves.
The outcome of this scheme is less privacy for the consumer. It doesn’t matter that Firefox doesn’t include exact identifying information. It still identifies demographics and other specifiers that can be used to target groups and their habits otherwise it would be as useful as an impression counter. This whole scheme is contradictory to how Mozilla has been portraying itself and the opted-in default is a ‘fuck you’ to anyone who cares about this. Putting the word privacy in the name does not mean it’s private. PPA changes nothing with regards to the advertising industry.
Saying ads are here to stay so you have to accept them or die, is an absurd false dichotomy.
Telling advertisers to fuck off works if your goal is to create a niche product tailored to people who care deeply about privacy already.
Reject ads wholesale and become irrelevant.
Absolute nonsense. How does rejecting ads or even including a default adblocker make Firefox any less relevant? I would hope most people would be more than happy to use a platform free from ads.
They are one of them. June 2024: Mozilla has acquired Anonym, […]. This strategic acquisition enables Mozilla […] deliver effective advertising solutions.
Thank you for a thoughtful post with citations and quotes. After reading the whole page by Mozilla, it seems like they’re taking steps to show advertisers how they can get what they want while preserving people’s privacy. I can live with that. They’re trying to build a win-win scenario.
I’ll still block ads. I’ll still reject cookies, but I feel like it’s a reasonable feature THAT I CAN SHUT OFF. I’m still in control of my browser! Great!
It appears in the release notes, though. Previously you would have been tracked. Now they try to anonymously return data to the tracker. So I do not see a reason to uncheck that flag.
Admittedly I am interpreting this feature from my gut. And you provide the sources I would have asked for. Appreciated.
It looks it it would be fun to mock the report generation API, and returns tons of garbage data (possibly negative numbers).
Given that it collects no additional user data, and the API in question is a new standard that will require sites to opt in, I think making it an opt-out is sensible. I guess they could make a popup about it, but I really think this concern is baseless FUD from people who haven’t read the details.

Why? I’m not in the business of making ad companies’ jobs easier.
Let’s be real, there’s no way PPA is going to be as valuable as the data that can be gathered by state of the art ad tech. So the ad companies that adopt this will be making a compromise to do so. How is this tech making their lives easier?
Also they have no incentive to develop this tech, so why would they? It’s not like Mozilla is doing work for them that they would have done anyway. If anything they’re probably worried that the tech will take off and then legislation will follow to force them to use it.
I personally am fine with making it opt-out, but I think it should be handled differently. This technology requires users trust, to have any chance of being successful. Enabling it without informing the user is not the way to gain it.
I would have put a little pop up explaining that they are trying to create a privacy preserving technology to measure ads with the goal of replacing privacy invasive technology. If the user doesn’t like it, it can be disabled in the settings afterwards.

The GDPR does not think so, does it?
