Is that the case with you, it doesn’t change the DNS?

Try following these steps to enable DNS over HTTPS on Firefox for Android:

Open chrome://geckoview/content/config.xhtml from the address bar
Look up network.trr.mode and set it to 3
Look up network.trr.uri and set its value to one of the addresses at the bottom of this page: DNS over HTTPS - Conforming Resolvers
Test page: DNS Leak Test - BrowserLeaks

I didn’t write that it’s Firefox beta 131, is it done the same way?

If my instructions didn’t work for you, you’re going to have to contact the developers of the extension you use.

Changing network.trr.mode to 3 sets DNS over HTTPS to Max Protection, which prevents DNS leaks with the Proton VPN extension.
