This gist explains how to setup DOH for Firefox using dnscrypt-proxy and nextdns.io.

Get a Linux server with a static IP (DO droplet would work). Download and install dnscrypt-proxy. Edit dnscrypt-proxy.toml (see wiki):

[local_doh]
listen_addresses = ['123.456.789.1:3000']
path = "/dns-query"
cert_file = "fullchain.pem"
cert_key_file = "privkey.pem"

    return multiply(gs_cofficient(v1, v2) , v1)
