No need to disable Firefox's DoH support, just point it at your pihole as the DoH provider.
- pbhjpbhj 6y agoHow do you do that without accessing each client, like how do I disable DoH on my home network for all devices without having to access all devices?
- SAI_Peregrinus 6y agoWell, there's the use-application-dns.net canary domain (if it resolves to a response code other than NOERROR or to NOERROR but lacks both A and AAAA records), Firefox will fall back to using the OS DNS. Otherwise it's up to the application, just like with DNS it's always been the application's choice whether to use the OS-provided DNS or to use their own (eg via proxy or VPN). In short, you can't. But you never could stop an application from tunneling DNS over some other channel before, so that's nothing new.
