What score does your browser(s) get?

I'll start: I got:

one in ~25000 browsers have the same fingerprint as yours

CreepJS is much better (and scarier) at fingerprinting you than EFF. I've not managed to completely fool it yet but I've got my score down to 0% trust, meaning the fingerprint it generates is pretty useless. I suspect the only way to totally fool it (by which I mean spoof my devices) would be to turn JS off completely.

On Safari 17 every time I visit the site it claims it's my first visit, despite a trust score of 57%. Not sure if I'm interpreting the results wrong or ITP is just doing its job.

[–] [email protected] 4 points 1 year ago

I'm not 100% sure but I don't think creep stores anything on its github incarnation so it'll always look like it's your first visit.

iOS 17 Safari (especially with enhanced fingerprint protection on) is really good at fingerprint protection. It rotates a few data points like canvas ID so that it makes you look like a new fingerprint each time.

Fingerprint analyzers can find out lots about your fingerprint that way, but if your fingerprint keeps changing, it becomes difficult to identify you. Unique fingerprints don’t mean anything if your fingerprint keeps changing.

Wow yea this seems really good. And scary. Too bad it doesn't seem to work with mullvad browser

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

I get 0% on CreepJS with default DDG browser set to "strict", with a crowd blending score of 27%.

I get 40.7% with Mull + adblocker and 66.5% with FF + adblocker

"Your browser has a unique fingerprint"...well that isn't good...

[–] [email protected] 5 points 1 year ago

Unique among the people who use that website. So if nobody else if you're configuration ever tried that website.... You would be unique

The bits of entropy are the more important parts of the results. The lower the bits the better

[–] [email protected] 2 points 1 year ago

Please also consider things like canvas spoofing. It will create a unique fingerprint that is different every time.

[–] [email protected] 10 points 1 year ago

I'm not sure how to read this report. It says my browser is unique and random with strong protections.

[–] [email protected] 9 points 1 year ago* (last edited 1 year ago) (1 children)

There is also fingerprint.com, which I tend to trust more since it's a company that literally sells fingerprinting tech to other companies.

It managed to identify me while using the Tor browser on "Safer" (doesn't work on "Safest" due to JS). Edit: this is likely due to an issue with my install, and not the browser itself.

[–] [email protected] 2 points 1 year ago (1 children)

How did it identify you via tor? Were you using the browser bundle? Completely vanilla?

Did you refresh your session between tests?

[–] [email protected] 2 points 1 year ago (1 children)

Completely vanilla, fully stopped and restarted the browser. This was right after the 13.0 update.

[–] [email protected] 4 points 1 year ago (4 children)

For what it's worth I just tested.

Tor browser 13.0.1, plus U-Block origin, fingerprint.com did not identify two different sessions

[–] [email protected] 2 points 1 year ago

I should test again then, not sure what happened

I got "unique among the 185,973 tested in the past 45 days"

Edit: this is using Firefox Android Nightly with UBlock + Canvas Blocker

[–] [email protected] 5 points 1 year ago

Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 4330.4 browsers have the same fingerprint as yours.

Currently, we estimate that your browser has a fingerprint that conveys 12.08 bits of identifying information.

mullvad vpn + mullvad browser + a bunch of extensions: 1:26830.0

fingerprint.com does not track me

[–] [email protected] 9 points 1 year ago (1 children)

Mullvad browser + extensions is pointless, might as well use LibreWolf or just harden Firefox yourself.

The point of the Mullvad browser is to not stand out from the crowd; by installing extensions you are definitely standing out.

[–] [email protected] 5 points 1 year ago (2 children)

librewolf doesn't do auto updates.

I don't need to harden firefox myself, mullvad comes pre harded.

[–] [email protected] 4 points 1 year ago

You're right. What I meant was that you lose Mullvad's fingerprinting resistance by installing extensions, but if you're only looking for a hardened Firefox with auto updates then it's fine.

[–] [email protected] 2 points 1 year ago (1 children)

Librewolf Flatpak autoupdates lol

[–] [email protected] 2 points 1 year ago

That's great! I'm glad you have a package management system that works for you!

https://librewolf.net/docs/faq/#how-often-do-you-update-librewolf

It should however be noted that LibreWolf does not have auto-update capabilities, and therefore it relies on package managers or users to apply them.

[–] [email protected] 6 points 1 year ago (1 children)

Am I looking for a high number or a low number?

Looks like Chrome randomized my fingerprint but Firefox doesn't. Does that mean I should be using chrome instead of FF?

[–] [email protected] 4 points 1 year ago (4 children)

Spoof your user-agent in FF

But also

Your browser has a nearly-unique fingerprint

I don't get it

[–] [email protected] 4 points 1 year ago

Almost no browser has the same fingerprint as yours, which makes it nearly unique.

[–] [email protected] 3 points 1 year ago

There's a couple issues going on here. Number one is it's unique amongst the people who go to EFFs website cover your tracks. That's not all of the internet users. Hell that's not even most of the internet users. It's pretty niche community.

The bits of identifying information are the critical key here. 16 bits, 2 ^ 16.. 65,000 different possibilities. Each piece of information you give, makes it a little bit easier to track you. Things like language, time zone.. The more bits, the easier it is to identify you. The less bits, the more you blend into the crowd.

This is why multiple people, including myself, have talked about fingerprint.com they're professional service, who's targeting websites, who want to track users. So they're incentivized to track as best as able.

Even if you've got a great EFF score, you should always check fingerprint.com, to see if they can track you.

Only one in 706.9 browsers have the same fingerprint as ~~yours~~ mine.

Is that bad? Or is this like golf.

[–] [email protected] 6 points 1 year ago* (last edited 1 year ago) (1 children)

The lower the number the better. That's pretty decent.

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

Not necessarily bad, the lower the number the harder it is to fingerprint you. In other words, your browser stands out much less and is less noticeable from the masses than the OPs browser.

Generally the more security/privacy tweaks and add-ons you apply to your browser the more secure it gets, but you tend to stand out from the masses more because of the changes, resulting in the 1 in 4,000 type stat. It becomes easier to differentiate your traffic from others.

Whether anonymity or security is more desirable depends on your threat model.

Edit: "Your browser fingerprint appears to be unique among the 186,867 tested in the past 45 days." Evidently I stand out quite a bit 😂

I've an unique fingerprint, but different fp results in every test run, with mostly wrong sys specs, only it shows correct my country, nothing else. Same in Browserleaks.

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago) (2 children)

On LibreWolf, which I use to surf daily, I got one in 180k+.

Afterwards, I tried Tor Browser -which is honestly almost never used- and this was a lot better at one in 6k+. Though this was only in "Safer" mode, I tried testing it on "Safest" afterwards, but an update screwed it up and I somehow couldn't get it back to its standard opening size.

Interestingly, my best result I got once again on LibreWolf. This time, I changed two things:

  1. Enable letterboxing
  2. Disable Javascript entirely through uBlock Origin

This resulted in a one in 800+. I am interested to know how Mullvad browser users fare on Mullvad VPN.

[–] [email protected] 2 points 1 year ago

I see. I too use similar settings on Librewolf: should try it.

[–] [email protected] 3 points 1 year ago (1 children)

0 because I have scripts disabled.

[–] [email protected] 2 points 1 year ago

Firefox mobile with various addons, most important of which is probably NoScript

Doesn't work with Javascript blocked.
