  • Version 3.0.0

    Released Nov 25, 2025 - 55.55 KB
    Works with firefox 78.0 and later
    Version 3.0 uses polymorphic obfuscation — instead of blocking trackers, we feed them fake data. Websites never break, anti-adblock never triggers.

    Works great standalone or paired with a VPN for maximum privacy.
