I did the tests on fingerprint.com/demo/ and https://coveryourtracks.eff.org/ and they both said I have a unique fingerprint, even when I enabled privacy.resistFingerprinting to True.
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.
So does Firefox make this more unique or something? I didn’t know this was a thing but I’m interested in privacy and it sound like something I should be looking into.
In essence: It makes it random. (Hence fingerprinting checkers find the ID uniqiue")
Although sometimes you need some features that interfere with it. I use the add-on “Toggle Resist fingerprinting” to easily toggle it off when I want a website to draw canvas (canva.com is a funny example lol) and then toggle it back when I’m done.
Some nice things, but it can interfere with some daily use cases: Timezone is changed to UTC. Canvas shows random data.
Nice rabbit hole read: https://wiki.mozilla.org/Security/Fingerprinting
(Its like Wikipedia. You can’t stop clicking on links to find out more xD)

Thanks!
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.
You’re absolutely right micro-optimization, I found that I did too much of that in 2022 and 23 and really cut down on that this year, I found that doing so is basically never worth it. I’m not gonna do that with privacy either, I’m focusing on what actions I can take that will make big improvements to my privacy rather than tweak every little thing.
Use Librewolf
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
- 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
