ESNI not activated after using just the DNS 1.1.1.1 on Windows 10

Currently I’m using Cloudflare’s DNS 1.1.1.1

But on the cloudflare website https://www.cloudflare.com/fr-fr/ssl/encrypted-sni/ they tell me that SNI is not encrypted. I don’t understand why.

Can you please explain me what the problem is ?

Regards,

I believe that it configured on your browser. I know Firefox supports it, I’m not sure about Chrome or other browsers. See https://blog.cloudflare.com/encrypt-that-sni-firefox-edition/

Same things in Firefox browser.

I have modified in about:config but nothing has changed.

Hmm, did you try closing the browser and opening it? Do you have any sort of system proxy?

Also what version of Firefox are you on? I believe ESNI is broken in Nightly at the moment

Yes, I have already restart my browser. The version of my Firefox browser is 84.0.1.
I don’t use some proxy.

This is capture of my chrome browser.
