  • Per-source permissions give very fine control over what a page may run
  • Includes anti-XSS and clickjacking protections beyond simple blocking
  • Targets fingerprinting APIs specifically instead of blocking scripts wholesale
  • Network boundary shield blocks public pages probing your local network
  • Many sites break until permissions are granted, which takes real effort
  • Not a good fit for people who want protection without configuration
