1900672 - DNS-over-HTTPS (DoH, TRR) provider OFF should default to fallbackProviderURI

Status: VERIFIED FIXED

(Core :: Networking: DNS, enhancement, P2)

Description

[Sean Kim [:sekim]]

Steps to reproduce:
Navigate to the "Privacy & Security" tab. In the "Enable secure DNS using" section, select "Increased Protection" (or "Max Protection"). Select NextDNS. Switch to "Off" and toggle back to "Increased Protection" (or "Max Protection").

Actual results:
The provider chosen in the "Choose provider" box is NextDNS.

Expected results:

The provider chosen should be "CIRA Canadian Shield (Default)", to maintain consistency with Bug 1861285.
This can be done by setting the network.trr.uri pref to fallbackProviderURI.

I think I could work on this, thanks. I could pick this one up once I am done with few other bugs, would this work?

Verified as fixed using Firefox 129.0b2 and the latest Nightly 130.0a1 on macOS 13, Windows 10 x64 and Ubuntu 22.04 - the provider chosen after switching to "Off" is the default one.
