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.

It constantly gives me 17.5 bits on several browsers firefox, nyxt, gnu icecat, librewolf...

[-] LambdaRX@sh.itjust.works 2 points 18 hours ago

Number of bits can also depend on your UI scaling, resolution and timezone.

Default Google Chrome embedded on Android with nothing configured and googled up.

17 bits.

[-] dwindling7373@feddit.it 17 points 2 days ago

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.

Not what I meant: https://github.com/arkenfox/user.js/wiki/3.3-Overrides-%5BTo-RFP-or-Not%5D#-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).

[-] underwire212@lemm.ee 3 points 1 day ago

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.

[-] ivn@jlai.lu 13 points 1 day ago* (last edited 1 day ago)

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.

9.3 bits / 1:628.3
(ipadOS / safari)

...how do they quantify 3/10 of a bit?..

[-] LambdaRX@sh.itjust.works 4 points 1 day ago* (last edited 1 day ago)

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)

[-] Viri4thus@feddit.org 54 points 2 days ago

If you have canvas randomisation turned on (firefox) you'll always be unique but also not traceable between sessions.

[-] ipkpjersi@lemmy.ml 4 points 1 day ago

How do you turn on canvas randomisation in Firefox? I can't seem to find anything about it.

[-] Muehe@lemmy.ml 2 points 1 day ago

I found this in about:config, defaults to true apparently: privacy.resistFingerprinting.randomDataOnCanvasExtract

But you have to enable privacy.resistFingerprinting for 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.

[-] fmstrat@lemmy.nowsci.com 11 points 2 days ago

Yup, canvas is heavily weighted in this test based on the results.

[-] Pika@sh.itjust.works 5 points 1 day ago

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

[-] ipkpjersi@lemmy.ml 4 points 1 day ago

I got 17.5 on my Desktop Firefox lol

[-] piracysails@lemm.ee 6 points 1 day ago
[-] CrabAndBroom@lemmy.ml 6 points 1 day ago

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.

[-] piracysails@lemm.ee 3 points 1 day ago

Could it be that the browser shares false information on purpose?

[-] Kidplayer_666@lemm.ee 56 points 2 days ago

I’m unique :) this ain’t great

[-] kusivittula@sopuli.xyz 21 points 2 days ago

its ok if your fingerprint changes on every browser startup

[-] Boomkop3@reddthat.com 7 points 2 days ago

...as long as you are blocking tracking cookies, and aren't on a session with a website that's tracking you.

Otherwise, you just have a nice unique hash in your cookies. A password manager could help here.

[-] broken_chatbot@lemmy.world 2 points 1 day ago

A password manager? Could you explain why?

[-] Boomkop3@reddthat.com 1 points 1 day ago

Cookies and other ways of keeping a session upright are kept by the browser. So unless you're mad enough to copy cookies between devices, they prove you're on the same device.

Using a password every time you log in, and letting your browser wipe everything on shutdown does not show websites wether you're on yhe same or another device.

[-] madargon@is-a.cat 0 points 1 day ago

@Boomkop3 @broken_chatbot Do you mean not keeping browser history actually makes big difference? I do that for few years but wasn't sure how much it really helped.

[-] Boomkop3@reddthat.com 1 points 1 day ago

That does not matter, cookies and other local web storage can though

[-] madargon@is-a.cat 0 points 23 hours ago

@Boomkop3 I mean full erase on shutdown, like in private window.

[-] Boomkop3@reddthat.com 1 points 17 hours ago

That includes that stuff, yep.

[-] Zerush@lemmy.ml 2 points 1 day ago
[-] OmegaLemmy@discuss.online 1 points 1 day ago

Didn't know Vivaldi had this capability, I just used it because it was the only decent browser with an on/off sidebar till zen

[-] Zerush@lemmy.ml 1 points 1 day ago

Not only the sidebar, you can tweak almost everything to your like.

[-] eleitl@lemm.ee 4 points 2 days ago

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.

[-] ExcessShiv@lemmy.dbzer0.com 27 points 2 days ago* (last edited 2 days ago)

With browser settings that actually let me use the internet in a way that's not overly cumbersome and annoying, I get 16bits or something and a "nearly unique fingerprint"

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.

[-] kekmacska@lemmy.zip 6 points 2 days ago

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

[-] SpatchyIsOnline@lemmy.world 1 points 7 hours ago

Does this spoofing change with every page you visit? If so that's really neat!

[-] muhyb@programming.dev 13 points 2 days ago* (last edited 2 days ago)

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:

[-] mac@lemm.ee 12 points 2 days ago* (last edited 2 days ago)

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.

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!

[-] ivn@jlai.lu 4 points 1 day ago

A VPN is unrelated, it changes your IP but the IP is not used to fingerprint.
