DNS-over-HTTPS in Firefox 60 and beyond
Firefox 60 recently released and with it came full support for DNS-over-HTTPS (DOH). By default, DOH is turned off but you can enable it quite easily.
- Go to
about:config - Search for
network.trr - Set
network.trr.modeto2(i.e. try DNS-over-HTTPS first and fallback on failure) - Set
network.trr.uritohttps://cloudflare-dns.com/dns-queryor any other provider you trust.
Caveats
Apparently, the current implementation may cause Firefox 60 to crash. This has been fixed in Firefox 61 which will release in June 2018. So if you encounter any crashes, set network.trr.mode back to 0 (i.e. off).
