1782697 - Presence of obsolete variable 'network.security.esni.enabled'

Status: RESOLVED INVALID

(Firefox :: Security, task)

Description

[lamalbrut]

CLASS | NSS/Libraries: report could not be sent against that class.

In Firefox v.104 | in about:config:

• network.dns.echconfig.enabled | true
• network.dns.use_https_rr_as_altsvc | true
• network.security.esni.enabled | false
• network.trr.mode | 2
• network.trr.uri | https://mozilla.cloudflare-dns.com/dns-query

Hello. While above mentioned settings prevail, a connection involving TLS v.1.3 to that page leads to the establishment of a secure SNI, which is indicated there by the presence of the mention sni=encrypted. This indicates

• the obsolescence of network.security.esni.enabled since that variable is proved not to be associated to a function.
• solely network.dns.echconfig.enabled governs the establishment of a secure SNI with respect to client.

As usual the presence of an obsolete variable is source of confusion and consequently eligible for removal,

In about:config, click the trash icon next to network.security.esni.enabled. That should remove it.

No removal from a single client could be meant here. Nothing but a removal from a next release was meant, yet it was quite obvious. After all...
