I used [Mullvad's guide](https://mullvad.net/en/help/dns-over-https-and-dns-over-tls#linux) to change the DNS in Linux Mint and it worked. But I have a question about Firefox's DNS over HTTPS settings. Can I turn it to *off* now that the whole operating system uses the Mullvad DNS?
Try Freetube, it still works well, even with videos that are age limited.
I checked it. I used the
adblock.dns.mullvad.netoption and adblocking works fine on all browsers without using adblock extensions. The checker on Mullvad’s website shows the DNS info as it should. I think maybe there’s no need for Firefox DNSoH settings anymore because the whole OS uses Mullvad DNS now. But I don’t know enough about DNS to be sure.
