Thank you everyone for this lively discussion.

So I guess just blocking isn’t acceptable for everyone.

What we could do instead is adding a checkbox to the new DNS settings section and call it “Enforce using IPFire as DNS resolver”.

That could then activate the following:

* Filter the domain name that Firefox uses to auto-enable DoH (*)

* Reject any client connecting to any other DNS server on the internet

Then, the only way to get DNS is to use the IPFire resolver. How is that?

(*) I have absolutely no idea what they were thinking to entirely throw DHCP out of the window and decide that they can configure clients. That is an absolute no go. I think Mozilla opened a very very bad can of worms here and there is no chance to put the lid back on. I find this absolutely ridiculous what we are considering doing, but Mozilla clearly had other priorities. I do get the idea of it, that everyone has access to a free internet, but that is already the case on my network. I have a DNS resolver that does things for me that I want, and they are simply breaking common practise here. And that not even for all users, but only for a random selection. And on top of all of this they partnered up with Cloudflare after self-hosting everything for privacy reasons for years. Absolute bollocks.
