Hello.

Why you stop support hardware only fingerprint?
It's good functions

https://github.com/Song-Li/cross_browser - maybe useful for extending the library

Hey, I looked at the source code and was questioning myself, why window.devicePixelRatio is put into parseInt.

There are some problems with it:

1. devicePixelRatio is a floating number, see the docs: https://developer.mozilla.org/en-US/docs/Web/API/Window/devicePixelRatio#value
2. parseInt expects a string. so window.devicePixelRatio.toString() should be the right way
3. Why at all parse it as a int? some ratio can be 1,5 or similar

Be careful, at least on Chrome Mac (Intel Mac OS 11.6.1 and Chrome 96) the results may be different on the same browser depending how the page was opened.
The 2 culprits are the mimeTypes and the plugins variables.

Example on a test page, if I copy-paste the address in a new Chrome tab I get this:
"mimeTypes": [ "application/pdf", "application/x-google-chrome-pdf", "application/x-nacl", "application/x-pnacl" ], "plugins": [ "Chrome PDF Plugin", "Chrome PDF Viewer", "Native Client" ],

Although if I click on a link that opens the exact same page in a Chrome tab I get this:
"mimeTypes": [ "application/pdf", "text/pdf" ], "plugins": [ "PDF Viewer", "Chrome PDF Viewer", "Chromium PDF Viewer", "Microsoft Edge PDF Viewer", "WebKit built-in PDF" ],

I did not dig further to understand why Chrome does not give the same info in these situations, but as a quick fix for that behavior you can remove those 2 const from the code.

I open the same browser on 2 different monitors (15.6 inch laptop and 25 inch secondary monitor) and I get two fingerprints.
Can you fix it?
Thank you very much

After updating browser (Firefox), calculated fingerprint has not changed, despite the version change

MacOS Safari on different Macbooks reports the same value.

I am trying to limit my chrome extension for one browser and i was using this library and fingerprint is changing what should we do?

Hello Damiano,

I've just discovered your library and I have taken it for a test run. Here's my results:

Edge Version 119.0.2151.58 (Official build) (64-bit) in normal mode

Fingerprint: 2803895700 (computed in 65 ms)
Fingerprint with hardwareOnly=true: 1801653769 (computed in 12 ms)
Fingerprint with enableWebgl=true: 1093115891 (computed in 288 ms)

Edge in private browsing

Fingerprint: 2352988901 (computed in 32 ms)
Fingerprint with hardwareOnly=true: 1801653769 (computed in 4 ms)
Fingerprint with enableWebgl=true: 1140287578 (computed in 80 ms)

Firefox 119.0.1 (64 bit) normal browsing

Fingerprint: 102973731 (computed in 101 ms)
Fingerprint with hardwareOnly=true: 2045863812 (computed in 9 ms)
Fingerprint with enableWebgl=true: 3031478298 (computed in 159 ms)

Firefox, clear all cache and normal browsing

Fingerprint: 102973731 (computed in 22 ms)
Fingerprint with hardwareOnly=true: 2045863812 (computed in 4 ms)
Fingerprint with enableWebgl=true: 3031478298 (computed in 58 ms)

Firefox private browsing

Fingerprint: 3324419382 (computed in 68 ms)
Fingerprint with hardwareOnly=true: 2045863812 (computed in 10 ms)
Fingerprint with enableWebgl=true: 1721380340 (computed in 114 ms)

Chromium Version 121.0.6100.0 (Developer Build) (64-bit) normal browsing

Fingerprint: 1776080590 (computed in 57 ms)
Fingerprint with hardwareOnly=true: 2109763731 (computed in 30 ms)
Fingerprint with enableWebgl=true: 3326289934 (computed in 188 ms)

after clearing the whole cache, normal browsing

Fingerprint: 1776080590 (computed in 87 ms)
Fingerprint with hardwareOnly=true: 2109763731 (computed in 10 ms)
Fingerprint with enableWebgl=true: 3326289934 (computed in 165 ms)

and private browsing

Fingerprint: 2246039315 (computed in 91 ms)
Fingerprint with hardwareOnly=true: 2109763731 (computed in 9 ms)
Fingerprint with enableWebgl=true: 2774134400 (computed in 149 ms)

So based on these results, I postulate that:

• every browser has its own fingerprints;
• all fingerprints remain the same after clearing the browser cache;
• the hardware only fingerprint is unaltered in private mode, all others change.

Is that correct? Are there any other findings?

Hey guys, I'm getting back on the official repo.
Do you have any feature request or use cause that forced you to fork the repository?

Would be awesome to be able to use this natively with Typescript
