Alternative TRR / Dns-over-Https-Server as a safer fallback

(5cb 1ksb7e7rrvbd) #1

currently the only fallback you have if you use doh in firefox is the (usually unencrypted) dns resolver dictated by your OS
i feel that (as usual with conventional dns) you should be allowed to provide firefox with a secondary doh server as a safer fallback compared to conventional dns
