And the salt means that your visitor's data are not trackable across websites. We don't actually have to give everyone's information away to advertiser's and data brokers.

This site didn't make a very good fingerprint.
🙂

The typing fingerprint is impressive, though.

It says I have 14,000 text-to-speech voices installed. I'm not too sure about that.
It says I have programmer fonts installed, and tells me I write code. I do not write code. Programmer fonts? Well, I likely have fixed width fonts. Does that make me a programmer?

Which is misleading since I'm pretty sure websites can still get quite a bit of information without JS.

I'm surprised it didn't try to read my location (which changes day to day and is almost always wrong, but a lot of sites ask for it anyway).

Exactly, if it is consistent. I randomize things like  user agent, available fonts and cloak other things too. Plus, every new, unrelated tab is its own container. Other things... The bastards may still get me somehow, but not with the tools on this site.

I read all the way down and never felt violated at all.
e.g.  it got my o/s right, but tz very wrong. Screen resolution was wrong too - I didn't take notes, but there were a few other dodgy things it 'knew' about me.  Overall, quite pleased! 🙂

Very educational. Going through TOR, changing my view screen size and user agent, didn't stop it recognising re-visits and correctly counting the number of visits. How? As the site states:

"On your first visit I stored a random tag, not in a cookie, but across localStorage, IndexedDB, the Cache API and window.name at once. I never learned your name; I just recognised the tag, and counted."

Clearing my browser history finally made me into a "new" visitor.

I wonder every stupid time I change duckduck to no AI and no other crap if it really matters. I also asked on AI something if selecting the button for no AI really stops it.

NOW ... I keep reading there's nothing I can do about it (I'm no geek) but is there something we can do about it?

But i am sure some of this information does not.

"You wiped sessionStorage, window.name, but localStorage, IndexedDB, Cache Storage still held the tag."(edit: later after waiting for the addon to actually clear it, it was just Cache Storage)
Cookie Autodelete failed me? Turned out deleting cache storage was disabled, but enabling it is not fixing it so far.. It's also annoying because probably it might be done without javascript also? (like add a unique url to be cached and see if it is there?)

Also my bubblewrap sandbox could hide fonts i guess?

Bit surprised Librewolf has cross-site referrers on by default. I turned on letterboxing, it did get some info wrong based on that. (maybe for sites i like, i want to give referrers in order to promote them lol)
