Enabling encrypted SNI in Firefox has no effect

Tested on: Linux (kernel 5.17.x) and Windows 11.

Web browser v.: Firefox 100.0

Hello. In the report of the analyse at Browsing Experience Security Check, the test covering Secure SNI does mention as follows: “Anybody listening on the wire can see the exact website you made a TLS connection to.” while it is dully expected that the exact website i made a TLS connection to, can not be seen.

ESNI is being depreciated in favor of ECH:

The ECH config is available in Firefox, but CF has only rolled it out in select zones (as of 10/2021).
