OS: Ubuntu 23.10 Firefox version: 119.0 Mozilla Firefox Snap for Ubuntu

I have DNS over HTTPS enabled and set to Default Protection in Firefox.

According to the following article (https://support.mozilla.org/en-US/kb/dns-over-https?as=u&utm_source=inproduct#w_why-would-a-network-tell-firefox-not-to-use-secure-dns) DNS over HTTPS should automatically switch to "Not Active" when connected to a VPN.

I am using the NordVPN CLI for linux and have found that when I connect to the VPN, Firefox DNS over HTTPS stays active and does not switch to "Not Active" like it is supposed to.

Does anyone know why this might be happening?

It's explained in this article: Canary domain - use-application-dns.net

ProtonVPN CLI has the expected behavior for me on Ubuntu 23.10 with the Firefox snap package, turning it on immediately causes DoH in "Default Protection" mode to switch status from "Active" to "Off". The system status bar shows "VPN" when connected.

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.
