Firefox already has an Enhanced Tracking Protection feature that blocks a list of known “fingerprinters” when your privacy settings are set to Standard (the default) or Strict. Fingerprinting Protection is a different, experimental feature under heavy development in Firefox. It is likely that it may degrade your Web experience so we recommend it only for those willing to test experimental features.
