Mozilla Faces EU Privacy Complaint Over Firefox's New Tracking Feature

Austrian advocacy group NOYB argues that Firefox's Privacy Preserving Attribution violates GDPR by tracking users without consent.

NOYB has filed a complaint with the Austrian data protection authority against Mozilla for enabling the Privacy Preserving Attribution (PPA) feature by default.
The PPA feature is intended to measure ad performance without using invasive cookies, but NOYB claims it still tracks user behavior without consent.
Mozilla defends the feature, stating it prevents any party, including Mozilla, from identifying individuals or their browsing activity.
NOYB demands Mozilla switch to an opt-in system and delete all data collected without user consent.
Mozilla acknowledges the initial code for PPA is included in Firefox 128 but insists it has not yet been activated and is currently in a limited test phase.
