GoKawiilMozilla ships new Firefox anti-fingerprinting protections based on in-house research
Mozilla has rolled out fingerprinting protections in Firefox designed to limit the browser and device details that trackers use to identify users without cookies. The work stems from a Mozilla research paper, accepted for CCS 2026, that measured which browser attributes contribute most to making users uniquely identifiable online. Mozilla has also published a companion website and browser test suite to let others examine the findings.
