Privacy complaint against Mozilla over Firefox user tracking

Vienna-based advocacy group NOYB, a digital rights group founded by privacy activist Max Schrems, said it has filed a complaint with the Austrian data protection authority against Mozilla, accusing the Firefox browser maker of tracking user behaviour on websites without consent. NOYB said Mozilla has enabled a so-called privacy preserving attribution (PPA) feature that turned the browser into a tracking tool for websites without directly telling its users.

While this may be less invasive than unlimited tracking, it still interferes with user rights under the EU’s privacy laws, NOYB said, adding that Firefox has turned on the feature by default.

Open-source Firefox was once a top browser choice among users due to its privacy features , but nowwith a low single-digit market share, lags market leader Google’s  Chrome, Apple’s Safari and Microsoft’s Edge.
