gold triad couple :
1) mull browser => for robust browser, you can add many addons here!
2) bromite => for fun only
3) smartcookies => anti social media browsing
note: everyone of them can be downloaded from f-droid

you can tweak 1,2 to use doh
> as in Indonesia it's always been blocked by government, even important site like imgur and reddit

1) mull browser (fork of ff mobile) tweak using about:config
network.trr.mode > 3
network.trr.bootstrapAddress > use ip adress like 1.1.1.1
> it's set and go

2) bromite just use url one, setting open in privacy :

Adguard: https://dns.adguard.com/dns-query
Cloudflare: https://cloudflare-dns.com/dns-query
Google RFC 8484: https://dns.google/dns-query
Google JSON API: https://dns.google/resolve
Open DNS: https://doh.opendns.com/dns-query
Secure DNS EU: https://doh.securedns.eu/dns-query
Quad 9: https://dns.quad9.net/dns-query

3) using custom hosts, yes smartcookies can use remote host
I'm using this url for helper : https://github.com/StevenBlack/hosts
> I pick unified + social

sadly last browser is yet to implement doh

LAST DISCLAIMER : I DON'T KNOW ANY REVIEW ABOUT THOSE BROWSER, YOU ARE AT YOUR OWN RISK
