    For me it is the other way around. That setting shows up in Chrome and Brave browsers, but not in Edge... I don't know what the problem is... Resetting everything to defaults and removing all Edge user account files made no difference.

    Does not work in chrome a lot depends on your ISP ( the explanation is quite technical and I don't fully understand it) , tried in Firefox it works, esni too, don't bother with chrome if u really needs this

    LOL! I was also thinking that Comcast is probably not the best choice RE privacy. Their posted privacy policy states they only share "non personal information":

    "As described in more detail below, Comcast may provide non-personal information to third parties that provide analytics services or participate in online advertising – either on behalf of Comcast or on their own. You may opt-out of these uses of non-personal information as explained in the “Cookies and Site Analytics” section below. Comcast will not provide your personal information to these advertisers unless you provide any required consent for us to do so."

    I am staying with Quad9 as well. Comcast made too much of a stink about this for me to trust them now. They are not currently my ISP but have been in the past and are an available option. I am actually paying someone else more to avoid going back to them. I'm not sure if Comcast has upgraded their DNS network in the recent past but there have been multiple instances where their DNS servers went down for extended periods of time so a more reliable DNS provider is always ideal with them anyway.

    Oddly enough, DOH still works for me on the current Chromium-based SlimJet using a command-line flag that no longer works on the equivalent Chromium build.

    Google is just catching up to the Chromium-based Bromite for Android, which has offered browser-level DOH for some time (although on the latest version it doesn't work for me on 8.1 but works fine on a 5.0 tablet).

    AdGuard for Desktop 7.5.1 now has the feature which to allow one to choose DNS providers, including the DoH (or regular, or DNSCrypt) setting.

    Quad9 with DoH here, across browsers ....

    Just some "strange thing" about using DNS - over - HTTPS.
    If I have my browser set to "secure" DNS - Cloudfare 1.1.1.1 , and use a VPN app, then,
    doileak shows the following:
    We received DNS requests from you via a DNS server from another AS (routable network) than your HTTP request. This could mean that your DNS requests are leaking.


    If I set my DNS to the Current Service Provider (my ISP), then, doileak shows:

    Your DNS configuration seems to be ok. All your DNS request(s) came from the same network as your HTTP request (or from anonymous DNS servers).

    Win 10
    I have DNS set to Cloudflare on Network Adapters.

    DNS over HTTPS
    Chrome, Edge Chromium, and Vivaldi provide two options-
    • Choose the current provider
    • Choose a provider (Custom) (Firefox provides this option only)
    If I choose the current provider option, https://browserleaks.com shows no DNS leaks.
    If I choose the custom option and select a provider, https://browserleaks.com shows DNS leaks. And as mentioned above, Firefox provides this option only, https://browserleaks.com shows DNS leaks with Firefox (if you set a provider).

    Is it leaking while you are using the MOST MARKETED ExpressVPN?
    Just kidding.
    Due to the Firefox (and Brave) DoH arrangement with Cloudfare, one must choose to
    a) either trust PUBLIC (and FREE) Cloudfare
    or
    b) your VPN service provider.

    Bare in mind that a VPN normally uses its own DNS so you don't leak outside the system, but if your browser is trying to use a different DNS you may end up leaking.
    If and when you opt to use DoH in the OS, any VPN you use should again be trying to ignore it or risk leaking.

    I edited the post and removed VPNs as users may think the mentioned ones couldn't protect against the DNS leaks.

    It seems-
    No DNS leaks with the "Choose the current provider" option.
    DNS leaks with the "Choose a provider" option.
