Details

Background: the current network.trr.excluded-domains feature documentation suggests that it can be used to allow the /etc/hosts file work by causing domains to be excluded from DNS over HTTPs and fall back to system DNS.

While this is an improvement over firefox DoH completely ignoring system DNS, it forces explicit repetition of re-routed domains and requires excessive work to integrate appropriately with the underlying system structure.

Request: extend the network.trr interface to include a field for a file path (or paths) to be set such that examine in addition to the explicit strings in network.trr.excluded-domains and network.trr.builtin-excluded-domains, such that firefox would be compatible with valid hosts file configurations.

Nice idea, maybe host files should have precedence over DNS over HTTPS resolve.

Thanks!
