If I have a certain phone model with updates applied. Is there something that distinguishes me from other people with the same phone and browser version other than the IP address?

Literally the comment below yours mentions GPU fingerprinting (0). Regardless of whether you won or lost the silicon lottery, you're different enough to be tracked.

I just tried to turn on `resistFingerprinting` in Firefox and it meant that my zoom preference for HN got reset every time I opened a new page (I have it set to 120% by default). Anyone know why? Bug?

You don't want to be fingerprinted means default options for everything Firefox can do it on

We need 2 classes of web. One for document based that doesn't require JS to run (secure). Insecure, all the SPA and anything that require JS to see the full content.

> We need 2 classes of web. One for document based that doesn't require JS to run (secure). I've wondered for a long time if a sort of posh gopher based on markdown with extensions would be able to make a comeback. Especially if it allowed for CSS.

But not current web CSS, please. It manages to be simultaneously overcomplicated (including enabling fingerprinting) and really bad at laying out text (e.g. still no baseline grid). A ‘markdown web’ style sheet should be more like document processor's character/paragraph styles. It also needs to be easily overridden for accessibility or alternate presentation, particularly around size and colour (a markdown-like format should already be fine for screen readers without styling). Aside: FFS, web people, if you're setting colours at all, respect @prefers-color-scheme and do not use the inverse for code blocks.

There's also the million-markdowns problem, and markdown's HTML embedding. This being Tuesday, I'd start with djot (without embedding), but Wednesday I might go for asciidoc.

Is anyone trying to tie users to multiple devices, and consequently identify both fingerprints as being from one user? I.e. Let's say I visit HN on both my laptop and on my mobile phone, each will have a very different fingerprint, but not only do I visit the same site on both devices but I am unlikely to do so simultaneously across the two devices, and there are likely to be other factors such as not visiting on eit…

Another technique you that could be used would be to look for distinct fingerprints that both have visited the same extremely niche web addresses. Someone is surely doing this already.

To me this seems extremely elitist. Non-technical people deserve to have their personal data stolen because they don't know about javascript for example?

Yeah? If they don't know how to operate a computer then they shouldn't be operating one. The same I would feel if someone without a licence crashed their car.

Using the web while being unfamiliar with Javascript is not analogous to driving without a license. It's closer to driving without being a mechanic.

Anyone know if there's been any forks of Chrome that enforce more privacy features? I know Chromium is a thing, but I doubt the builds for Chromium (except when tweaked by some Linux distros) do much like Firefox does.

I only use Chrome to test some things, or to create a completely isolated browser session disconnected from my use of Firefox.

Look, forget about threat models. It's relatively trivial these days to avoid fingerprinting attacks if you want to (as a private, web browsing individual). I use fingerprinting actively in enterprise apps as a form of silent 3FA. It's a useful backstop. If I have a user who forgot their password but retrieves it via email, I'll usually let them pass if their fingerprint matches one of their priors; otherwise my soft…

You seem to have a conflict of interest here. How can you accept this for employee/employer but at the same time say it's not ok for a person to submit fingerprinting? Employees are also persons.

Using the IP address & user agent alone already gives you nearly 100 % accuracy, so the fact that they can re-identify you when these things stay identical isn't surprising at all. I tested that website as well and if you take care to rotate your IP address their re-identification rate becomes abysmal, especially if you're using a privacy-focused browser and extensions like Privacy Badger / uBlock.

Exactly. IP address identification is the elephant in the room that the article just briefly mentions. Nearly all websites that want to target adds to you use that. It's just so simple to use, you can't switch it off like you can with cookies, except of course by using a VPN but almost nobody does that.

I often see the narrative on here that consumer VPN providers are almost useless for privacy due to other fingerprinting methods, which I've never really bought.
