Use Tor Browser. Don't waste your life on micro-optimisation. You will get a lot more privacy with stuff like getting all your friends on Signal/SimpleX, etc.

Use Librewolf

Both my browser and network level dns blocker blocked the test attacker site from loading but in general there are 2 approaches to this: minimize your fingerprint data points or change them to blend in with the crowd.

I think for the most part selectivly blocking js and cookies will do a lot for you. You can also block the canvas and limit fonts too. I'd also recommend a vpn as they can associate it with your ip too.

Tor Browser is the best way.

I finally made a Lemmy account just to comment on this 😅

When this option is active, of course your fingerprint is unique because of how it works.

Every time a website fingerprints you with this option turned on, firefox makes sure that the ID is as unique as possible, so no correlation can happen. 😊 Verify this by visiting that site two times and check the hash to make sure it change between the two requests.

EDIT: fingerprint.com probably use Cookies and/or localstorage so the ID is the same when refreshing, but Firefox have protection in place for cross-site tracking and cookie sandboxing, etc (I won’t pretend like I know how everything work), but those protections helps against that type of services from what I recall.

You can try playing with Arkenfox, installing uBlock Origin, fiddling with about:config, and giving yourself an aneurysm...

...or you could try Mullvad Browser. It's a fork of Firefox, co-developed by Mullvad and The Tor Project, with impressive fingerprinting resistance (according to Cover Your Tracks). It's like Tor Browser without Tor.

Also, install NoScript. It helps a lot.

Try out Librewolf it's Firefox fork which is hardened out of the box so you don't have to mess with settings too much.

There's a collection of similar extensions that worked for me to throw fingerprint.com off each time I opened an incognito window. Idk I've heard that having too many extensions can actually make the fingerprint problem worse. If this is a bad approach, I'm sure someone will correct me :D

use Tor Browser.

If your concern is fingerprinting, that is undeniably the best there is out of the box.

If you want Tor Browser without having to use the Tor Network, Mullvad is basically just that; Tor Browser without the Network.

Use LibreWold and/or Mullvad. Done.

• Use a fork of Firefox (librewolf), or a different open source browser
  • even if you modify Firefox to remove all telemetry, Mozilla are bad actors, and will update to add new telemetry like Anonym or Cliqz by default after an update. Unless you really trust your package maintainer, use a fork or a different browser
• Force a common useragent
• Disable javascript everywhere, or use a browser without javascript, whenever possible
  • trying to defend against fingerprinting with javascript enabled is futile, even things like your number of cpu threads (navigator.hardwareConcurrency), list of fonts, webgl support, supported codecs, browser permissions, and variations in canvas rendering can be used in fingerprinting
    • tor browser is the only project I know of that can come close to avoiding fingerprinting with javascript, but even then you're advised to avoid using javascript with tor browser
  • use 3rd party clients for things like youtube that would normally need javascript
