The ISPs in my country is starting to censor sites and I am currently using DNS over HTTPS (DoH) to circumvent it. But to my latest knowledge, the SNI in TLS sends the hostname in plaintext. CloudFlare is currently experimenting on ESNI as the solution. Does the latest Firefox or the Nightly version, support ESNI. If Yes then, how can I check its status? If No then, Am I correct to assume that it will be experimented on the later Nightly Versions?

Thank You.
