Changes and updates

  • Update Tor Browser to 12.5.

    Tor Browser 12.5 has a new circuit view and better information about onion services.

  • Prevent Tor Browser to access information about other Tor circuits. (#19740)

  • Make the error when scanning the QR code of a bridge more consistent. (#19737)
