Firefox fingerprint defense

Run the patched Firefox release through Playwright Juggler with engine-level parity controls.

Firefox fingerprint defense — contract and behavior

  • The documented Firefox release includes pref registration, webdriver suppression, WebGL, screen and outer-window overrides, and the Juggler navigation patch.
  • WSession routes browser: firefox through findCustomBrowser and launches the matching binary with weles.fingerprint.* preferences.
  • persona.ts rotates Chromium and Firefox to diversify BoringSSL and NSS network fingerprints as well as browser surfaces.
  • The manual integration workflow probes each private Firefox release against the trajectory driver.

Stay in the loop. Never miss out.
