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.

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).
