The headline is factually incorrect. The ISPs of DoH users can still happily see user's destination IPs and hostnames (via SNI, even when the traffic goes to a shared cloudflare IP).

Firefox implemented ESNI, which encrypts the hostnames in the SNI handshake, last year.

Yup. This can be fixed by enabling ESNI (network.security.esni.enabled in about:config), I don't see why they aren't pushing that change at the same time.

Edit: ESNI is still a draft, definitely not a safe default.

I forced a reaload of all my tabs (dozens), while sniffing my traffic. Not a single one used encrypted sni.

Because Firefox's move is a media stunt in order to get them a lot of positive coverage and paint them as a "privacy-focused" browser.

Not only that, Firefox have such a tiny percent if the market that anything they do, that could benefit Google, is just better to Google then to Firefox.

In the Mozilla/Cloudflare brave new world, Cloudflare is front-ending and MITMing all HTTPs in any case... so the IP isn't informative.
