Mozilla has released Firefox 145 with enhanced anti-fingerprinting protections, reducing the number of users vulnerable to digital fingerprinting. The new features are initially available in Private Browsing Mode and Enhanced Tracking Protection (ETP) Strict mode, and will later be enabled by default. These updates aim to mitigate tracking techniques that identify users across websites and sessions, even when cookies are blocked. The new protections include blocking requests for installed fonts, hardware details, processor cores, multi-touch support, and adjusting reported screen resolution. These measures reduce the trackability of users to 20%, down from 35% in the previous phase. Mozilla emphasizes the importance of balancing privacy with usability, ensuring that legitimate website features remain functional.
