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
- Search for
2(i.e. try DNS-over-HTTPS first and fallback on failure)
https://cloudflare-dns.com/dns-queryor any other provider you trust.
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).
