Hello,
Currently the Blokada DNS beta does not provide a clear text DNS option. I understand that this is probably what you’re looking for.
You may however use a system wide encryption (Blokada DNS included) in Windows by subscribing to Blokada Plus.
Another option is to use the encrypted Blokada DNS in any web browser that supports DoH, such as Firefox.
Simply enter: https://dns.Blokada.org/dns-query in the custom DoH settings.
