Description of the issue:
Set up: DoH working in normal Brave Window.
Failure: File -> New Private Window
Error: DNS requests are send to port 53/udp in clear and DoH is no longer being used in private window. Oops.
DoH to continue to work inside Private Window
Brave Version( check
Similar problem is with private VPN extensions such as NordVPN: When opening a new private window then the default extension configuration is to DISABLE NordVPN. This can be controlled under extensions settings (“Settings -> Extensions -> Manage Extensions -> NordVPN -> Details -> Allow in private”). This however is hard to find and a trap for any consumer who uses NordVPN and trusts that ‘private window’ would make it more private
Expencted behaviour: NordVPN default should be to be available in private window.
Even worse, and somewhat related: “New Private Window with TOR” also disables NordVPN meaning that TOR traffic goes directly via the ISP and not via NordVPN - possible fatal for users who are using TOR in countries where TOR is not allowed and are expecting the TOR traffic to go through NordVPN first.
