Through the Tor Uplift Project,[1] Tor Browser's Fingerprinting Protection feature is now available in Firefox on desktop and Android. The feature makes Firefox hide some pieces of identifying information from the sites you interact with, such as your timezone (which is set to UTC), some of your fonts, your keyboard layout/language, and parts of your user agent (for example, your browser version is set to the latest ESR version).[2]
To enable Fingerprinting Protection in Firefox, go to about:config and set privacy.resistFingerprinting to true.
Some Firefox forks enable Fingerprinting Protection by default, including LibreWolf[3] (desktop) and Mull[4] (Android). If you are on Android, the release version of Firefox does not include access to about:config, and you'll need to either switch to Firefox Beta/Nightly or use a fork like Mull, Fennec F-Droid, or Iceraven to take advantage of this feature.
