Mozilla accused of tracking users in Firefox without consent

NOYB filed a complaint with Austria’s DSB alleging Mozilla’s Firefox Privacy-Preserving Attribution (PPA) feature tracks users without consent, despite being billed as a privacy-friendly ad measurement tool. Mozilla counters that PPA was included in Firefox 128 but not activated for end users, is limited to a test on the Mozilla Developer Network, shares only aggregated data, and can be disabled in settings; the company acknowledges it should have engaged more with external stakeholders and aims to clarify its approach.
