For Waterfox for Android I exposed the setting by default and also added an addition DNS over Oblivious HTTP setting (DoOH) which uses Fastly as the relay (they host and control it, for privacy sanitisation) and Cloudflare as the resolver.
But more importantly, there's a system wide DoH setting in Android (or at least in GrapheneOS). I don't see why it would preferable to only configure DoH in the browser.
Am i the only one for which about:config does nothing on Firefox on Android ?
With the workaround in the sibling comment it can be accessed in both Firefox stable and Firefox Focus.
This allowed access from the standard settings page which you can see in this release, it’s the same setting just exposed instead of hidden.
I think Nimbus experiments also might have exposed the setting.
How is the latency?
> The first thing that we can say with confidence is that the additional encryption is marginal. We know this because we randomly selected 10,000 domains from the Tranco million dataset and measured both encryption of the A record with a different public key, as well as its decryption. The additional cost between a proxied DoH query/response and its ODoH counterpart is consistently less than 1ms at the 99th percentile.
