In Case you missed the comments on #385935
Users of Mullvad VPN and Mullvad Browser can enable the feature to block dangerous and unwanted content such as advertisements, social media, malware, trackers, etc.
If you are NOT using any Mullvad service, you can still block incoming content. All you have to do is change the DNS record in your client. Mullvad describes exactly how to do this in your client on their webpage https://mullvad.net/de/help/dns-over-https-and-dns-over-tls
On Android, go to Settings - Network & Internet - Private DNS and set the hostname you want to use (see the table on Mullvad webpage).
The same or a very similar service is also available for free from Cloudflare. It is supposedly even faster than Google's DNS service (4.4.4.4 and 8.8.8.8). Cloudflare claims: "the Internet's fastest, privacy-first public DNS resolver".
You can either use Cloudflare's app (Android, iPhone, Mac, Windows, and Linux):
Or ignore the app and just set your DNS as usual (Android, iPhone, Mac, Windows, Linux):

The full DNS config options are:
Malware Blocking Only Primary DNS: 1.1.1.2 Secondary DNS: 1.0.0.2
Malware and Adult Content Primary DNS: 1.1.1.3 Secondary DNS: 1.0.0.3
For IPv6 use:
Malware Blocking Only Primary DNS: 2606:4700:4700::1112 Secondary DNS: 2606:4700:4700::1002
Malware and Adult Content Primary DNS: 2606:4700:4700::1113 Secondary DNS: 2606:4700:4700::1003

And yes it works. I would recommend to ignore the app and just set your DNS manually. The app is for people who do not know how to set a DNS address. If you want to read even more read: https://blog.cloudflare.com/announcing-the-results-of-the-1-1-1-1-public-dns-resolver-privacy-examination/

I was sceptical about this, but it seems to be true. From the page you linked:
You can use this privacy-enhancing service even if you are not a Mullvad customer.
Very useful information, thanks!

Not saying this is inferior in any way, but what's the advantage of using Mullvad's DNS compared to NextDNS (jurisdictional arguments aside)?
