Agreed. Just looked up about trr nonsense and found this 'setting':

> network.trr.excluded-domains

> Comma separated list of domain names to be resolved using the native resolver instead of TRR. Users may add domains they wish to exclude from TRR to this pref. This pref can be used to make /etc/hosts works with DNS over HTTPS in Firefox. Setting network.trr.excluded-domains to include host names from /etc/hosts will make them fall back to platform DNS, which will use the rules in /etc/hosts.

So, rather than using the hosts file, network admins & devs now have to specify 'special sauce' in FF too?

I'm not buying DoH for this reason alone, because it throws out a lot of legacy (albeit always regarded as hokey) for no good reason. If FFox is doing it's own DNS stuff is MUST (at least) do hosts file resolution, imho. Otherwise it leaks names, which kinda defeats one of the main the purposes of DoH: which is to maintain critical privacy in places where it's being abused.

This is so true. FireFox is terrible at spaffing private info at search engines.

Breaking DNS is madness IMHO. Its just more sites that dont work on FF.

Broken is not more secure, its just broken.
