Firefox is enabling DNS-over-HTTPS (DoH) for some users starting this month, and it will use Cloudflare by default:

DoH (IETF RFC8484) allows Firefox to send DNS requests as normal-looking HTTPS traffic to special DoH-compatible DNS servers (called DoH resolvers). Basically, it hides DNS requests inside the normal deluge of HTTPS data. [DoH doesn't encrypt DNS requests. That's a different protocol, namely DNS-over-TLS, aka DoT].

By default, Firefox ships with support for relaying encrypted DoH requests via Cloudflare's DoH resolver, but users can change it to any DoH resolver they want [see here].

When DoH support is enabled in Firefox, the browser will ignore DNS settings set in the operating system, and use the browser-set DoH resolver. By moving DNS server settings from the OS to the browser level, and by encrypting the DNS traffic, DoH effectively hides DNS traffic from internet service providers (ISPs), local parental control software, antivirus software, enterprise firewalls and traffic filters, and about any other third-party that tries to intercept and sniff a user's traffic.

Firefox Plans Controversial New Encryption Setting For Millions, And Update Starts This Month

A presentation from BT on the "Potential ISP Challenges with DNS over HTTPS" earlier this year warned that DoH will reduce the ability to derive cybersecurity intelligence from malware activity and DNS insight, open new attack opportunities to hackers, and result in an inability to [fulfill] government mandated regulation or court orders as potential concerns. And so the change will foster serious debate. [...] The U.S. is first, but the rest of the world will follow. A spokesperson for the U.K. Internet Services Providers' Association told me that "the debate on DNS over HTTPS (DoH) is evidently a topic that polarizes opinion. However, our position is clear. ISPA believes that bringing in DoH by default would be harmful for online safety, cyber security and consumer choice."

DNS-over-HTTPS is the next default protection coming to Firefox

Mozilla will be rolling out DoH in what it calls "fallback mode" later this month. This means that if domain name look-ups using DoH fail, Firefox will revert back to using the default operating system DNS. Similarly, if Firefox detects that parental controls or enterprise policies are in effect, Firefox will disable DoH.

    So Firefox by default is going to start leaking my internal network information to an untrusted (to me) 3rd party? And introduce DNS lookup delays as well?

    I've been a long time Firefox supporter. But this. This is where I drop Firefox. But what to turn to? Edge? Chrome is not an option.

      The unwashed masses have no idea what this change means if they even hear about it at all. Both Mozilla and Cloudflare are counting on the fact that few will know how to override this. Silently taking over the end users dns settings with an "on by default" override is no different than installing a keylogger. Mozilla is rolling out software that will silently redirect all your dns traffic to a 3rd party of their choosing. This can be classified as malware activity in my book.

        The "unwashed masses" are already having their DNS data slurped up by their ISP and google (8.8.8.8) or whatever etc.

        Silently taking over the end users dns settings with an "on by default" override is no different than installing a keylogger.

        Maybe... If the keylogger they install replaces the keylogger you already have installed that sends all its keystrokes to your ISP with one that sends all your keystrokes to a new place that explicitly promises not to use them.

        Where the keylogger analogy breaks down is that you don't NEED all your keystrokes logged online; but you kind of DO need all your DNS queries handled.

        but everyone else are vicitims of what I would classify as criminal activity.

        Again, they already are victims. And this probably victimizes them less.

        Both Mozilla and Cloudflare are counting on the fact that few will know how to override this.

        If you don't know how to override this then you are probably already a victim. Mozilla is trying to make a bad situation less bad.

          What I'm hearing you say is: "Everyone's privacy is already compromised so it's ok for Mozilla to do it too".

          Nope, not buyin that one. People who originally jumped on with Firefox did so because they are privacy conscious. They may not know how to stop all the other avenues tracking them but they should at least be able to trust that Firefox isn't doing anything nefarious in the background. That trust is now gone. Firefox no longer distinguishes itself from all the other major players that are intentionally and for profit selling the data mining rights to their user base.

            You have to send your DNS queries out to someone. There's no way around that. If you trust mozilla enough to use their browser, then its not unreasonable to trust them with the DNS queries from the browser.

            Mozilla's chosen provider may not meet your absolutist perfect standards (and who exactly are you using that DOES?!) ; but the cloudflare policies in place are better than 99% of what most people using DNS are getting. Mozilla is not "compromising your privacy", they are sending your DNS queries to an entity that is promising greater privacy than 99% of what most people currently have. They aren't monetizing it, they aren't doing what others are doing with it at all. Cloudflare's policies are pretty reasonable 24 hour retention and some basic aggregate trending is pretty reasonable to maintain a service like this.

            a) How is Mozilla's solution not better than what joe-sixpack is currently doing? (And if it is better than why are you against it?)

              The fact of the matter is that if this was a random extension that did this, it would be in violation of the A.M.O. guidelines. You may trust Mozilla, the people who make extensions, or both, or neither, but it is hypocritical, at best, to have different standards for the two of them.

              You have to send your DNS queries out to someone.

              The dns root servers are that someone. There's no good reason to send your queries to a for profit corporation that admits they collect and aggregate your information. If Mozilla really wanted to be privacy conscious they wouldn't have used a for profit firm. In my opinion, Mozilla has been looking desperately for cash streams to pay their increasingly top heavy salaries and Cloudflare is one such revenue source. I suspect the reason Mozilla caved and made hyperlink ping tracking mandatory also involved similar advertiser or aggregator kick backs.

              Like Google, it seems Mozilla built up a user base by promising they can be trusted and when it hit a certain mass they started cashing out in ways that are hard for the end user to see.

              And to answer your questions:

              a) How is Mozilla's solution not better than what joe-sixpack is currently doing? (And if it is better than why are you against it?)

              Currently, users have control over their networks. Most choose not to exercise that control, but those who do know that when they choose a dns provider it holds true for their entire network. It's expected behavior that the dns on your network applies everywhere. Mozilla is subverting that by inserting hidden non browser functionality into Firefox that is both silent and outside the average persons control. And I say hidden because from what I've seen, there is nothing in the browsers options that someone might see to turn it off or even know it's there. And does anyone really expect an end user to know how to create a "canary domain" that would disable this hidden DoH system? Not a chance, and both Mozilla and Cloudflare know it.

              b) What exactly are you holding up as an even better alternative?

              They could have solved the issue entirely by doing a couple things:
              1) Make it opt in
              2) Provide an easy to find browser option to turn it off - don't deceitfully hide this thing and make it difficult to turn off
              3) If the user opts in, give them a randomized list of DNS providers, with notations about which are "for profit corporations" as well as a place to enter custom providers, and let the user pick the one they want.

          Firefox users, by and large, were attracted to the browser for privacy reasons - an alternative to the invasive Chrome browser. It's not deragatory to assume that most people are not technically savy just as it's not derogatory to assume that most people aren't surgeons. Technical details at this level will make most peoples eyes glaze over. But not being technically savy doesn't mean they can't show a desire for privacy by choosing Firefox. And it is a betrayal of that trust for Mozilla to push a narrative of "enchanced privacy" when they are in fact undermining that privacy for profit.

          If Mozilla wants to take the high road then they should go with an "opt in" process. When folks update their copy of Firefox, present them with the facts and then ASK THEM if they want to turn over control of their name server. Don't sneak it in quietly, hide it from the options dialog, and require them to perform highly technical gymnastics in order to turn it off.

          Again, this is the company that is mandating hyperlink track in an upcoming release. No overrrides. And again they're touting it as "privacy enhancing" because if everyone is tracked somehow your more protected.

          Mozilla has lost their way. They're in it for the money now. There's no difference between them and Google Chrome anymore.

            I doubt that. People, by and large, were attracted to FF because of the feature set. Those who are after privacy are likely using Brave, the DDG browser, EPIC, Safari, Chromium, or Tor. And probably a VPN.

            It's not deragatory to assume that most people are not technically savy
            Of course not. Most people are not savvy enough to even change the DNS setting from the default, they don't even understand what DNS is. Most people don't understand (or care) that Facebook and/or Google spies on everything they do. And you expect them to change the settings to a more private DNS?

            My ISP doesn't know what my DNS queries are, because I use a VPN that has its own DNS and swears that they don't log queries. But you gotta trust someone, somewhere, and I have decided to trust them. You seem to think that Cloudflare is less trustworthy than Comcast, ATT, CenturyLink. I think it is not possible to be less trustworthy than those companies (unless maybe your name is Zuckerberg).

There's the new Opera, Vivaldi, Brave, Blisk (which I never heard of until I just did this search), Colibri, Epic, and Ungoogled Chromium (another new one, to me). There are a couple dozen more on that zdnet page, which didn't warrant their own analysis pages. Pick your poison. Or, take them all for a test drive before choosing.

        I am using waterfox lately. I like it. The problem though is that many financial websites refuse to work with it on security grounds - they ask to upgrade to the latest firefox. I ended up using Chrome for thouse because at that point everything is already tracked to death.

          Good point. Not all sites work as well with all browsers. At some point, you have to make compromises.

          As I've pointed out before, I have several browsers installed. Half a dozen Firefox derivatives, half a dozen more Chrome-likes, and a couple ancient oddballs that have their own peculiarities.

          Only one of those browsers has any persistent data in it's settings. When I have to visit a financial page, I use that browser, so that I can access my long-ass passwords, etc. I don't use that browser to browse, to listen to videos, or much of anything else. It's there to deal with "official" sites. No other browser knows where to look for financial information, or those passwords, or even user names for those sites. What's more, using multiple browsers makes it more difficult to be fingerprinted, or tracked via other methods. I have little idea if my bank makes any attempt to track my browsing and shopping online, but if none of that data is contained within my browser used for banking, then that browser cannot give them that data.

          All of that may sound a bit paranoid, huh? Well, yeah, I think we have reason to be paranoid. If you aren't at least a 3 paranoid on a scale of 1 to 10, then you're not paying attention to the world around you. :^)

            I use virtual machines for different purposes. For finance and such, I have a dedicated one that I use for nothing else. Even then, I don't trust my browser with passwords. I wrote my own little password generator many years ago and I use it. Not that it is better then others available, but I am protected by obscurity here.

            Other virtual machines I typically have are the main one for general browsing and work, and one for visiting dangerous places. The host OS is just lightly used - mostly to show something to the border agents.

            I do need a better DNS solution though.

    You probably don't want Edge. Microsoft gave up and they're putting in the Chrome engine. Unfortunately, I have no good suggestions. I'm pretty fed up with all operating systems and all web browsers.

    Try https://ipleak.net [ipleak.net]

    It probably already does so via WebRTC
