These links list literally SOME and not ALL cases that need encryption.

I'm afraid I don't see your point here, please elaborate.

Your point is "this should be applied to ALL sites", while your argument for it is "because it is relevant for SOME sites".

HTTPS is brittle. HTTP is insecure, but will run forever. This move will literally kill the old web.

One more reason to move to gopher:// and gemini://

gemini didn't ring any bell for me, for those like me,

You're right, I guess the question is did they bother before. If normal DNS works fine for 95% of users, the hurdle of implementing a non-standard workaround is too much. If DOH is the norm, then the hurdle becomes lower. Of course you can just drop a rule blocking the IP address on your firewall, which will probably work for a while.

I would argue that the hurdle of bypassing DNS-based content blocking was already so vanishingly small that it doesn't make any sense to impede useful and practical privacy technologies on that basis. You could make the exact same kind of argument about widespread use of HTTPS for example. Do we want to allow encryption technology if it means the enemy can use it too? As a society we have agreed that encryption is a…

That doesn't hold up under scrutiny. My pihole blocks ~11% of domain lookups (blocking 1000 queries per day for our household), turning it off vastly increases the unwanted content. It might seem is logical a ready hurdle, but it's a hurdle that practically works.

I don't follow the reasoning that says this is a small barrier to malware so we'll remove it.

What are we, end users, getting out of routing all our domain lookups to Cloudflare and ceding control of filtering?

You cannot say that certificates are reliably free (especially in the long run), if there's only one entity providing them and that entity is dependent on corporate sponsors.

We can't say that a true statement is true just because there's a chance that at some point it becomes false?

By that logic Lehman Brothers stock was a great investment on the 14 September 2008.

As a user, what is the increased admin burden for using DoH, assuming you don't want to implement network level content blocking? Basically none. What is the burden for using HTTPS assuming you DO want to be able to inspect and block HTTPS resources at a network level? Very extensive compared to plain HTTP.

>assuming you don't want to implement network level content blocking? // Who doesn't want that? I have a pihole (and use OpenDNS). Bypassed it all yesterday, as an experiment, to look at an anime site my eldest started using and immediately was hit with a pretty impressive and convincing phishing attempt (mimicking my ISP). Pretty much all of us on HN seem to use some form of 'DNS' based filtering (pihole, or even ju…

I don't want it and I don't recommend it to my peers. I also don't think DNS-based content blocking is really as popular as the PiHole community would say. I use client-side content blocking like uBO instead, which I imagine is overwhelmingly the more common solution, and it is also more powerful and effective (and easier to use).

UK ISPs having mandatory DNS blocking is a great example of why DoH is important. The user should decide what they want, not the network operator.

Perhaps widespread use of encryption technologies means I can't do content blocking on proprietary appliances like the Chromecast for example. I think that's a necessary evil and I just won't buy such an appliance if it's that big of a problem. Only legislation can really fix that kind of problem anyway, it doesn't really matter whether Firefox implements DoH or not.

> As a developer … most of our internal development sites are http only. As a developer, should you not work against an environment closer to production behaviours? Otherwise you might miss performance issues (due to different caching behaviours between http/https) or other problems until your code is released.

Its not always the code you work on. It might be other internal services or sites.

All our internal services are HTTPS. Then if a new hack is found to weaken wireless protocols we have that extra line of protection. Security in depth.

We serve strongly regulated industries and are subject to in-depth audits by clients on occasion, so perhaps my level of paranoia would be less warranted elsewhere. I'd still HTTPS everything though, even if the potential payoff is small because the required effort is too.

I want my OS to do DNS - including DOH, not my browser. I want a single source for my DNS I want my network to tell me a DNS server to use. As I own my computer I can override that, but much of the time I want to use the network provided DNS server.

What you want would make censorship and surveillance easier against the vast majority of people. Networks I'm on shouldn't be able to tell which CloudFlare-hosted site I'm visiting, or to block some of them without blocking them all. Letting the network give me a DNS resolver instead of using a known-good one would allow exactly those bad things.

OK, what if you own the network? The corollary to that is 'you shouldn't be allowed to stop devices on your network from accessing malware, or exfiltrating data'.

> The main problem with keeping sites http is that someone in the middle can modify the content and inject arbitrary code I keep hearing this as a plausible excuse, yet I've never seen any proof of such. non-https does make it possible but has anyone got any source where someone has been victim of such attacks?

First link, Kazakhstan even tried to MITM people with HTTPS, second injecting ads by ISP. [1] https://www.privateinternetaccess.com/blog/kazakhstan-tries-... [2] https://security.stackexchange.com/questions/157828/my-isp-b...

Kazakhstan did not do that to inject ads. I believe that they wanted to block webpages on a granular level (for example some specific blogs). Right now they block complete websites, because it's not possible to find out which URL user is visiting.

It obviously is. Having just an HTML site now becomes more expensive for no clear reason. Which makes more sense for people to check out Gemini.

You're aware that Gemini mandates a recent version of TLS in the protocol specification, right?

Self-signed certificates are first class citizens. Section 4.2 of the spec.

I run my own networks and my own devices, I choose what options go in my DHCP server If I were on a hostile network (say a hotel), then sure, I'll ignore their DNS server and use my own (or indeed just punch my way out via a VPN), but most of the time I use friendly networks, and I don't want to have to configure 20 different applications on a dozen different boxes to use a DNS provider of my choice. There's a reason…

You are able to run own network and have the know how to do so, typical physical Firefox users cannot. Given your knowledge you can disable or even build firefox with DoH disabled , it is a sensible default for vast majority of users who do not know what DHCP is, or control their network. It cannotis trivial configuration for people who can control and do not want the DoH service provider given by Firefox. Also many…

Why should Firefox want enable users and devices to bypass network owners configuration in this way? A company should control their network, just as a home network's owner should have control.
