There was another time I got into a very serious ontological discussion with a fairly senior engineer about what the difference was between taxes and fines and they didn’t understand there was a difference,” he said.

I run all my stuff in a private tab nowadays. And nuke all cookies etc each session.

Also, make sure I have anti-fingerprinting enabled.

With a VPN.

The only annoying thing is I get a few texts/emails saying "A new device just accessed your account. Was it you?". Yes, yes it was. And I'm not relying on a cookie or fingerprinting for security.

Private tabs do nothing for the backend, your ISP, browser, search engine, and any sites you visit, can still see everything you do. All private tabs do is they don't save history or cookies on your frontend.

VPN hides your data from your ISP, but there are still workarounds. Multi-hop can make you harder to triangulate though.

You still need to use a privacy-centric browser and search engine or else the ones you use can still send information about you back to their servers where they can build a profile on you. They won't have your real IP address as long as you never connect without a VPN, but any little data they collect on you can be collated with the rest to profile you and potentially identify you.

Even with browsers like firefox or waterfox, you still need to enable all of the security settings or else there are gaps that can be exploited. HTTPS-only mode, DNS over HTTPS, anti-tracking extensions, etc...

Even then, I wouldn't be surprised if there's an unseen gap somewhere. But it's a lot better than using google and microsoft and no vpn.

Also, browsers still send so much unique data that they can be reasonably well fingerprinted. I don't really know all the things, but you can combine info such as OS, browser version, window size, list of extensions, HTTP request headers, timezone, etc...
Plus you could also track behavior.
And even with VPN some analysis might be able to figure out what you're looking at based on traffic patterns.

Holy shit, that's a lot of data. I had no idea they could see what language packs I have installed on my keyboard. I have a pretty unique combination of languages, so that probably makes me really easy to identify across platforms.

Is there an easy way to disable or block fingerprinting?
