[SOLVED] DNS-over-HTTPS quetion

I check firefox (78.6.1 esr) preference settings. I am sure that the option "Enable DNS over HTTPS" is checked and is configured to cloudflare 1.1.1.1 (This is also in /etc/resolve.conf).

But when check cloudflare page https://1.1.1.1/help

It shows following configuration that I wonder what I miss (so Using DNS over HTTPS (DoH) would be set to Yes).

Code:Using DNS over HTTPS (DoH) Noos is debian bullseye/sid
