Mozilla announced yesterday that NextDNS has been added to the list of official partners for Firefox's DNS-over-HTTPS feature. NextDNS is a new DNS provider that launched in March 2019 that is "a fully customizable, modern, and secure DNS provider" according to Mozilla.
The service is listed as beta currently on the NextDNS website and is completely free during the beta period. NextDNS offers options to enable filtering lists to block known malicious sites, trackers, and other unwanted requests.
The company plans to introduce a paid option after the beta period ends for $1.99 per month for unlimited DNS queries. Free customers are limited to 300,000 DNS queries per month. It is unclear what is going to happen when the limit is reached.

I have been testing NextDNS for about three weeks you can black list, and white list sites, there is also built in lists you can select.

Right now I have these three set to be blocked and there is a lot more to choose from;


Security
Contains the worst of the worst. Sites that are known to distribute malware, launch phishing attacks or botnet command-and-control servers used to communicate with already infected machines.
Ads & Trackers
Includes the most comprehensive ads and trackers blocking lists out there. Also blocks third-party trackers disguising as first-party trackers.
State Surveillance
Block domains that are known to be involved in spying.

It keeps track of your queries which you can view under Analytics

So far I have 288,818 queries and 36, 607 of them got blocked:

Security 1
Ads & Trackers 34, 095
CNAME Cloaking Blocklist 2,512

It also shows you who you are connecting to and how many times, I put this DNS on my router so it shows what devices have been making queries as well.

This is a great tool that gives you more control and a lot more information on your internet usage, and it is pretty fast when I tested it using the DNS Benchmark.

This is my record for the last 3 months. But this is for my Android smartphone only, it would be a lot more if I used it on my PC as well. I use a lot of filter lists so it covers almost everything that can be blocked by DNS. It's amazing 👌

Thanks for sharing your experience. Would it be possible to show the types of content it lets you filter? also how effective is the mapping between content type in config vs actual content type - does it match a spade to a spade, or spades get mapped as animals occasionally ?

I tried NextDNS based on this NextDNS added CNAME Uncloaking support, becomes the first cross-platform solution to the problem and thishttps://medium.com/nextdns/cname-cloaking-the-dangerous-disguise-of-third-party-trackers-195205dc522a.
I found it broke some websites and had some other trouble. The free beta version will most likely be a fairly short trial if you use it on desktop.

According to the two articles, their approach is or will prove superior to ad blocking extensions, presumably even the Firefox API available to µBO and others. Maybe only time will tell which strategy or platform is best for dealing with cname cloaking.

It's host based blocking so it has its limitation. It lets you choose among many filter lists provider. You can visit their site and trial it without creating an account, that should help you understand it better.

I'm not so sure of this DoH/DoT thing. IMO, I'll choose a dedicated VPN instead and let the provider handles the DNS queries through its dedicated metal servers. A few VPN providers do come with good content filters e.g. Perfect Privacy, NordVPN etc. And malicious scripts, phishing sites, browser fingerprinting and other browser privacy-associated issues still need to be addressed by the user either through a 3rd-party software or the use of extensions

Do you know if there's any website to confirm if Adguard doh is enabled? I know cloudflare has one.
The Adguard DNS setup page How to set up AdGuard DNS will show you if you're using its DNS and configuration type but won't specify DOH. If you enable it in your OS and you have the appropriate flag enabled in Chromium you can be sure it's working at the Adguard page. For use in FF (without enabling in OS) the test will be accurate as well, though again it won't indicate DOH.

@Azure For Firefox, after setting your desired DoH, in about:config change "network.trr.mode" to 3 and set "network.trr.bootstrapAddress" to the ip4 address of your DoH provider. This would ensure no matter what Firefox is always using DoH.

network.trr.mode modes explained:
  • 0 - Off (default). use standard native resolving only (don't use TRR at all)
  • 1 - Reserved (used to be Race mode)
  • 2 - First. Use TRR first, and only if the name resolve fails use the native resolver as a fallback.
  • 3 - Only. Only use TRR. Never use the native (This mode also requires the bootstrapAddress pref to be set)
  • 4 - Reserved (used to be Shadow mode)
  • 5 - Off by choice. This is the same as 0 but marks it as done by choice and not done by default.
*TRR = Trusted Recursive Resolver
