Misconceptions about Firefox's Privacy Preserving Ad Measurement

Mozilla has introduced the Privacy Preserving Attribution API in Firefox 128.0 to combat invasive tracking by AdTech companies. This feature aims to shift metrics and tracking from individuals to ad campaigns, ensuring privacy while allowing advertisers to measure campaign success. The API collects noisy aggregate metrics locally in the browser, which are then sent to a Distributed Aggregation Protocol (DAP) provider for anonymized reporting. By decoupling metric collection from ad networks, individual tracking is avoided. The initiative is part of a larger effort to eliminate invasive tracking, complementing legislative measures like GDPR. Despite initial pushback, enabling Privacy Preserving Attribution by default benefits user privacy by offering a less invasive tracking option. Users concerned about tracking can modify settings in Firefox or use additional tools like uBlock Origin for enhanced protection. Overall, the API represents a positive step towards preserving user privacy in the online advertising ecosystem.

Just because someone objects to a thing doesn't mean that they don't understand that thing.

The biggest problems i have with it:

- it's only opt out on desktop

- on mobile there seems to be no way to opt out at all unless you go hacking around to enable about:config

I understand what they're trying to do, i just don't agree with it. I've given up on trusting the ad industry. I'll never try to compromise with them again.

"Advertisers gonna be evil" is not a reason to keep appeasing them in my opinion.
