On Librewolf i got 16.48 bits of information, on TOR browser 10.32 bits, but on Tails I managed to get only 9.3 bits.
If you have canvas randomisation turned on (firefox) you’ll always be unique but also not traceable between sessions.
How do you turn on canvas randomisation in Firefox? I can’t seem to find anything about it.
I found this in about:config, defaults to true apparently:
privacy.resistFingerprinting.randomDataOnCanvasExtractBut you have to enable
privacy.resistFingerprintingfor it to work first. I enabled that and now the EFF test says “randomized” for the hashes but also Lemmy went from dark to light theme somehow.privacy.resistFingerprinting breaks a lot more than just themes. Many of the weird problems reported in Firefox (and forks) are just from enabling it.
It has some pros but also TONNES of cons. Everything from a completely blank page to wrong timestamps to poor textures and so much more. Sometimes you will be flagged as a bot and prompted with literally infinite puzzles, thus effectively banning you from a website.
Some of these problems get fixed but new ones also get born. I personally use it but I also expect breakage and worse performance.
Yup, canvas is heavily weighted in this test based on the results.
Am I wrong to assume trying to blend in is a worse and contradictory strategy than trying to actively protect yourself from tracking?
If you want to not be unique, use default setting chrome without adblock. Your browser will look just like anybody else’s, but they will literally know who you are.
On the opposite side of the spectrum, you lock everything down and spike as a very special browser and… that’s all they know.
Privacy vs. anonymity
Not what I meant: https://github.com/arkenfox/user.js/wiki/3.3-Overrides-[To-RFP-or-Not]#-fingerprinting
"If you do nothing on desktop, you are already uniquely identifiable - screen, window and font metrics alone are probably enough - add timezone name, preferred languages, and several dozen other metrics and it is game over. Here is a link to the results of a study done in 2016 showing a 99.24% unique hit rate (and that is excluding IP addresses).
Changing a few prefs from default is not going to make you “more unique” - there is no such thing."
Basically making yourself less unique is impossible so there’s no sensible tradeoff to be made (other than in the context of Tor and Mullvad Browser).
Right. The question is whether they can attach what they know to an identity. Depends on your threat model which goal you need to achieve.
But then they can know a lot more since they don’t even need to drop a cookie to track you. But that’s a different threat model.
"Your browser fingerprint appears to be unique among the 183,614 tested in the past 45 days.
Currently, we estimate that your browser has a fingerprint that conveys at least 17.49 bits of identifying information."
Chat am I cooked?
Same result here. I’m using Gnome-web, which is already pretty niche, so that probably really lowers my score.
Default Google Chrome embedded on Android with nothing configured and googled up.
17 bits.
It constantly gives me 17.5 bits on several browsers firefox, nyxt, gnu icecat, librewolf…
Number of bits can also depend on your UI scaling, resolution and timezone.
Despite having strong protection according to these results, I always get unique fingerprinting from them. Which is scary.
Edit: Now I tried Tor on my desktop and got:
Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 628.7 browsers have the same fingerprint as yours. Currently, we estimate that your browser has a fingerprint that conveys 9.3 bits of identifying information.
Your browser fingerprint appears to be unique among the 183,951 tested in the past 45 days.
Currently, we estimate that your browser has a fingerprint that conveys at least 17.49 bits of identifying information.
well shoot my mobile failed that test lmao
I got 17,49 as well!
I got exactly that number too, but also when I looked at the detailed results section lots of it was incorrect. It got that I was on some sort of Linux and using some sort of FF variant, but things like time zone, plugins, screen resolution and system fonts were all wrong.
So sending out 17.49 bits of largely identifying bullshit is still okay I think lol.
Could it be that the browser shares false information on purpose?
I got 17.5 on my Desktop Firefox lol
Your browser fingerprint appears to be unique among the 183,996 tested in the past 45 days.
:(
Huh mullvad browser got me the lowest overall. 10.44 bits and a non-unique fingerprint.
Compared against:
- Firefox with arkenfox user.js (macOS)
- Tor (macOS and android)
- Vanadium (android)
- Cromite (android)
- Mull (different than mullvad) (android)
I do a vast majority of my browsing on my phone, unfortunately. Vanadium scored the best (on mobile), but it not having extensions (dark reader is a must) and the navigation bar not being movable to the bottom of the screen keeps me on Mull.
I don’t love using mullvad for day to day browsing as I can’t whitelist specific cookies to retain. Don’t love having to re 2fa daily.
12.67 from Safari/iPhone, without changing any settings. This is my most commonly used browser
16.47 on Cromite. But most of the identify information is not even true, almost everything is spoofed. User agent, timezone, operating system, browser name, screen size and color depth, device, even the battery percentage
Does this spoofing change with every page you visit? If so that’s really neat!
screen size, system time, color depth, battery percentage does
9.3 bits / 1:628.3
(ipadOS / safari)…how do they quantify 3/10 of a bit?..
They probably give entropy value, average number of, yes or no, questions that are needed to identify You. (Guess all the information that your browser provided)
Vanadium: Your Results Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 61101.0 browsers have the same fingerprint as yours.
Currently, we estimate that your browser has a fingerprint that conveys 15.9 bits of identifying information.
I get 8.44 bits (1 in 347.34 browsers). I use Firefox with Arkenfox user.js applied on top, with some of my own custom overrides.
However, I think the biggest factor could be because I have Ublock Origin set to medium-hard mode (block 1st party scripts, 3rd party scripts and 3rd party iframes by default on all websites), so the lack of JavaScript heavily affects what non-whitelisted websites can track. I did whitelist 1st-party scripts on the main domain for this test (coveryourtracks.eff.org), but all the ‘tracker’ site redirects stay off the whitelist.
I actually had to allow Ublock Origin to temporarily visit the tracker sites for the test to properly finish–otherwise it gives me a big warning that I’m about to visit a domain on the filter list.
with budget vpn on: one in 22756.25 browsers have the same fingerprint as yours
with budget vpn off and just apple safebrowsing on: one in 20231.22 browsers have the same fingerprint as yours.
i have the worst vpn!
A VPN is unrelated, it changes your IP but the IP is not used to fingerprint.
i got the same results every time i ran it with or without the VPN so you can say that but it’s obviously having an impact.
just enabling/disabling the VPN between tests and clicking the link again.
It might have a side effect but it’s still unrelated and useless for the purpose at hand.
so to what do you attribute the difference in score, when it’s different with the VPN on vs off I wonder?
I’m amused at your insistence it does nothing when it clearly does.
That’s side effects, the difference is irrelevant anyway.
I insist because I think it’s important to understand this, both for you and for people reading these comments. The whole point of fingerprinting is to be able to track users without relying on cookies or IP. Changing IP does not protect against fingerprinting. I don’t want people to be mislead by your comment and think they are going to avoid tracking by just taking a better VPN.
You can read more here:
https://coveryourtracks.eff.org/about#browser-fingerprinting
“Browser fingerprinting” is a method of tracking web browsers by the configuration and settings information they make visible to websites, rather than traditional tracking methods such as IP addresses and unique cookies.
And you can check the source code to see there is no mention of IP address:
https://github.com/EFForg/cover-your-tracks/blob/master/fingerprint/fingerprint_helper.py
if it changes the score than how is it meaningless? the score is worthless?
It’s not worthless but it’s on only an indication, an example.
Isn’t the score change similar to the one you have when toggling Apple safebrowsing? (whatever that is)
A probable explanation is that your VPN client is somehow changing some of your browser settings. The VPN client, not the VPN itself.
Just check the detailed results to see what’s changed between the two. Whatever it is it could be changed manually, it’s does not require a VPN to change. But you probably don’t want to change it because your score with a VPN is worse than without.
But this has nothing to do with a VPN being the best or the worse.
