The page isn't loading for me. https://web.archive.org/web/20180601141754/https://trac.torp... ( https://archive.org/donate )

it worked after a few tries for me. I believe its just serverload, keep trying or try later

I'm sure it is just overloaded. But there's no point kicking it when it's down. Use a mirror for now.

Hopefully other browsers are encouraged to do something similar also, else Mozilla will effectively control the destiny of Tor

Brave is already working on Tor private tabs though it won't have the same fingerprinting/first-party isolation guarantees as with a Tor Browser, https://github.com/brave/browser-laptop/labels/feature/tor Should be shipping soon https://twitter.com/BrendanEich/status/984231250104733696

The CA/B Forum rules only allow EV certificates for .onion, so even if Let's Encrypt wanted they couldn't give out .onion certificates without getting that changed first.

Oh right, that is a good point. I suppose Digicert is the only option for now then.

Perhaps the Tor team or an affiliate could set up a simplified CA and have a public CA cert restricted to .onion that folks could install as a work around to having browsers trust it by default.

This is the biggest misconception about Tor. Tor provides anonymity, but any node (EDIT: any exit node) can read what you're sending if it's not encrypted. You need both.

nitpick: exit node. The ones on the way can't, neither can any if you access hidden services.

Yes, sorry, I should have specified.

I've been waiting for this for years. Good job convincing Mozilla to do this! Good idea to standardize the spec, too.

I hope they give a good name to this new super-private mode (which actually isn't too bad of a name, either).

I also hope they don't just implement a "more private" mode in Firefox, but also a more hardened mode for Tor. The Tor mode in Firefox should use the strictest possible sandboxing technologies available to them from the operating system (file system virtualization, etc).

I'm even talking about those new fancy hypervisor-based micro-VMs in Windows 10, which I believe they are called Krypton containers, and it's what Edge uses within the Application Guard context. Although if the users have to enable Hyper-V/Micro-VMs first in Windows, then maybe this hardening mechanism should be optional, but encouraged. Otherwise, it should probably be the default.

Oh, and this hardened mode should use a different process for every tab/extension, too, by default, just like Chrome does. I still don't think Mozilla's "hybrid" approach makes it as secure as Chrome (which is why it's a hybrid/compromise for lower memory usage).

Good, now if only we could have bitorrent baked in...

EDIT: I mean baked in in the browser like tor, not baked in tor. Although interesting, it's really not my priority.

>Fortunately HTTPS adoption is much better now :) It's HSTS what we need in 2018

I disagree. Ive seen HSTS applied to things like Windows 10 updates, to prevent users from seeing what exactly your OS is sending to the mothership. Ideally, we should be able to see exactly the content being exfiltrated, and choose to allow/disallow. But the moment we use tools like ettercap or mitmssl, it kills the session and we can't see the data. HSTS seems more "self cutting" than useful at this juncture.

The use of HSTS is a way to suggest to your clients that they use SSL for that domain - for all requests within a time span (which could be "forever").

If anything, the vendors you mention should be applauded for taking that step towards a more secure distribution of updates. Not enforcing SSL makes malware injection through updates way way easier.

Debian introduced HTTPS repos a while back as an option, but not by default. Other distros already offer it.

That's definitely not true if your endpoint you're talking to is an *.onion . A connection to an Onion is encrypted to the destination. That also means if you were running, say NodeRed with authentication, sending credentials "over the clear" (no SSL cert, because stupidity) it's not actually sent over the clear. It's encrypted to the public key relating to your onion address. Now, if you're using Public Internet->To…

Cool, now let me start an ephemeral v3 onion service from JS and have it reachable via WebRTC by a peer who has their own. It's the perfect tech marriage, removes signalling servers and NAT busters, but may be a bit taxing on directory servers and too slow to use for media streams (but I'll take data channels only).

Honest question: is bittorrent even still a thing?
