Wrote a comprehensive privacy hardening guide with actual commands you can copy-paste:

  • Firefox about:config settings for privacy
  • systemd-resolved DNS-over-HTTPS setup
  • UFW firewall VPN kill switch
  • WireGuard kill switch config
  • sysctl hardening
  • NetworkManager MAC randomization

Also has Windows and macOS sections. And a Privacy Audit tool to test your setup.

Free, no tracking. Feedback welcome.
