Mozilla is rolling out significant privacy enhancements in Firefox 145, aimed at reducing digital fingerprinting risks for users. Initially, these new protections will be available only in Private Browsing Mode and Enhanced Tracking Protection (ETP) Strict mode, before becoming the default setting after further testing. Fingerprinting allows trackers to identify users across different websites and sessions, even when cookies are disabled. By using subtle details like browser version, screen resolution, and installed fonts, trackers can create unique profiles for individual users. The existing anti-fingerprinting measures in Firefox, branded as ‘Phase 1 Protections,’ have already reduced user trackability from 65% to about 35%. The upcoming ‘Phase 2’ protections introduce more stringent blocking of techniques that reveal hardware and software details. New features include adding random noise to background images when accessed, limiting font usage to standard OS fonts, and reporting processor cores as a fixed number (2). With these updates, only 20% of users will still be uniquely fingerprinted and tracked. Mozilla emphasizes a balance between privacy and usability, acknowledging that overly aggressive blocking could disrupt legitimate website functions. Users experiencing issues with the new protections can disable them for specific sites. It's also notable that Firefox 145 will no longer support a 32-bit Linux version, a decision made due to declining demand. Users can already access the installer from Mozilla's FTP server ahead of the official release.
