Can't enable TLS 1.3

Kuphostiwe

I have downloaded both the Nightly and Firefox Dev Edition but non of them can enable TLS 1.3

I have use "about:config" to config the tls max version to "4" (which should be TLS1.3 supported) but nothing happens. I try the https://nghttp2.org:13443/ (which is TLS1.3 supported if I connect it by openssl directly).
