    Interesting reads:

    Centralised DoH is bad for privacy, in 2019 and beyond

    ...we haven’t been very analytical about what moving and encrypting DNS does for privacy.

    The article above reads very much with the unstated subtext - Firefox are the naughty people because they're effectively mandating Cloudflare.

    And, in this instance, I agree with that. The problem with the FF default is that it's not respecting what the OS and DHCP might be specifying, and that's potentially dangerous.

    DNS over HTTPS Will Give You Back Privacy that Big ISPs Fought to Take Away

    I agree that if user manually specified OS DNS address then Firefox should respect that. On the other hand:
    1. ISP may be considered as threat to privacy, especially in USA. In UE it is a less of a problem because of GDPR
    2. DHCP is a protocol that does not use cryptography to check for integrity of received packets. That is a problem, because adversary can send spoofed DHCP packets. If it is on your private, wired infrastructure it is less of a problem, but when you connect to public Wifi, especially public unencrypted Wifi networks it is a real threat.

    Well, if people don't like cloudflare they can always change the DOH server to something else with few clicks (at least in firefox)
    Code:
    https://en.wikipedia.org/wiki/Public_recursive_name_server
    In the future, there will be products/services (free or paid) with always encrypted DNS for those who know what they want.
    And for the rest of the masses there is an option to always enable encrypted DNS if they so wishes.

    ISPs have to figure out some other ways to squeeze money from their poor users ....

    Well, on public Wifi, use of a VPN is rather desirable, and should over-ride the dhcp's (nominal) choice of DNS. I also tend to use Firejail with nailed-up DNS resolution.

    VPN is something user must choose and pay for in advance. Most people don't have VPN subscription. Also VPN generates additional overhead, so it degrades performance, especially if Wifi signal is not great and there is a considerable amount of packet loss.

    DNS-over-HTTPS will eventually roll out in all major browsers, despite ISP opposition
    DoH support is already present in all major browsers. Users just have to enable it and configure it

    That happens if the connection is not there first. It checks to see if there is a connection before enabling.
    If you change the service to delayed start it can help (worked for me).

    Oh BTW. Firefox does actually let you set your own preferred resolver, and is actually easier to change than chrome.

    The news that Micro$oft will bolt DoH into the system is excellent !
    This stuff should not be handled differently in all apps or chaos will reign.
    However I think I will still stick with DNSCrypt due to the flexibility and functionality which MS will not bother with.

    I'm not changing nothing, I want it to work out of the box so that I can install it at people's computers without having to worry over whether or not the service runs properly or not.

    "Because configuring Firefox to use a custom DoH resolver instead of Cloudflare is extremely complex and out of the reach of most Firefox users, Mozilla has been criticized over the past few months for favoring Cloudflare in the detriment of other DoH providers."


    "Extremely complex"? There is nothing difficult about manually entering the IP for NextDNS into the DNS-over-HTTPS settings of Firefox as far as I can tell. Am I missing something?

    People are lazy. That's the only possible explanation.

    Because if you say that people are too dump to type the IP address into the input field
    then you will quickly lose faith into humanity and it get's really depressing quickly .......

    Or like Neil DeGrasse Tyson said:

    "My great fear is that we've in fact been visited by intelligent aliens, but they chose not to make contact, on the conclusion that there's no sign of intelligent life on Earth"

    :D
