Right. I'm getting tired of seeing people dump on Firefox and Mozilla about this thing in the release notes:
Firefox now supports the experimental Privacy Preserving Attribution API, which provides an alternative to user tracking for ad attribution. This experiment is only enabled via origin trial and can be disabled in the new Website Advertising Preferences section in the Privacy and Security settings.
What is this? And why is it not something to get heated about?
Attribution is how advertisers know how to pay the right site owner when someone clicks on their ad. It's important for ad-supported sites that clicks get attributed.
Right now, attribution is basically incompatible with protecting privacy. Advertisers use every method of tracking you can name, and some you can't, to provide accurate attribution.
The Privacy Preserving Attribution API is an experimental way of informing an advertiser that someone clicked on an ad on a given site without leaking that it was you, specifically, who did that. Specifically, ads using the API ask Firefox to remember that they were seen, on what sites, and to what sites they lead. Then, when the user visits the destination site, the destination site asks Firefox to generate a report and submit it via a separate service that mixes your report with reports from other people and forwards these aggregated reports in large batches. Any traces that might be unique to you are lost in the crowd.
This is still experimental, being enabled by Mozilla on a site-by-site basis as developers request it. It's not a free-for-all yet, and I can only find one entry on Bugzilla of a site who's requested it.
If it's such a great thing for users, why isn't Mozilla shouting from the rooftops how they've improved things, instead of it being enabled automatically?
What blows my mind is how people are crapping on Mozilla just constantly. Yeah sure they can do better. But also it’s the only real alternative to total domination from Chrome and all the dozens if not hundreds of rebuilds/ripoffs/reskins. It’s bizarre that they providing such a negative perspective on the basically the last bastion of an open web.
This constant negative attitude just boggles my mind. I’m happy with Firefox and Thunderbird with the functionality and features. Most of all the internet desperately needs diversity in the browser space.
For what it’s worth. I’m also skeptical of what they’re doing in the ad space. But I’m willing to give them the benefit of the doubt because the internet sadly runs on ads for the vast majority of it. If they’re trying to at least bring something ethical to that space they have my support. Once they have a fair chunk of the market and don’t rely on the Google antitrust protection racket to survive we’ll talk about how to do better.
It does not matter how you feel about Googzilla. Spyware is spyware. And this is just one of many aspects of spyware built into and sneakily added by Googzilla.
That's why there are forks like LibreWolf that remove that nonsense, because people aren't sitting back and letting Googzilla run it into the ground.
Of course, Firefox already partitioned (and can block, if you enable Strict Tracking Protection and accept some extra breakage) cookies, so those more invasive ads were already neutered. Unlike e.g. Chrome, whose Topics API proactively reports characteristics about you before you click an ad, and does so while third-party cookies are still allowed too.
This seems to assume that advertisers don't want our identifying information, and are clamoring for an alternative to tracking that lets them measure ad performance anonymously, which is just not true. Being able to uniquely identify users and target them is a feature, and getting more data points from the browser just helps add to their profiles.
