:rolleyes:All those extensions to fingerprinting functionality.

@Sampei.Nihira, Don't worry, it's all right... I've already told you that there are no duplicates in the functions... everything is fine.

""Your browser has a randomized fingerprint" - what extension (Trace?) or setting you use in Chrome, please... (this is firefox maybe)... " - sorry to repeat my precedent question to you :rolleyes:....

Font Fingerprint Defender has nothing to do with remote fonts, it protects against websites that scan your system fonts. It makes a random font fingerprint, which is very good !

@D.Draker, one of the functions in "Fingerprint Spoofing" extension is "font" already - it makes a random font fingerprint, you see...

Other functions of this unique ext. I use for now: canvas, audio, this famous font, more, timezone, random (this one make the random fonts!), logs. Very cute ext., I've adopted it recently and I hope you will at least try it... I love it!:cheerleader:

Here, its Size 59.43 KiB: https://chrome.google.com/webstore/detail/fingerprint-spoofing/ljdekjlhpjggcjblfgpijbkmpihjfkni?hl=en-US

ARTICLE: Demo: Disabling JavaScript Won’t Save You from Fingerprinting

https://fingerprint.com/blog/disabling-javascript-wont-stop-fingerprinting/

no-javascript-fingerprinting.jpg

Fingerprinting is a way to identify website users without using cookies or data storage. Instead, device properties like language and installed fonts are used to create highly accurate, unique identifiers that work even if the browser has incognito mode turned on.

A common misconception is that disabling JavaScript can prevent fingerprinting. Since advertisers and bad actors use it for ad targeting and tracking your online activity, it’s a natural (albeit incorrect) assumption that disabling JavaScript will protect you against fingerprinting. In this article, we will demonstrate that fingerprinting can occur even in the absence of JavaScript.

Check out the demo to see it in action:

No-JS Fingerprinting Demo https://noscriptfingerprint.com/ - passed already in the Post #2...

The demo should show the same fingerprint, even if visitors attempt to conceal their identities using the following methods (among others):

Requesting desktop mode in mobile browsers

Spoofing the user agent

Using incognito mode

Changing the internet connection

These are just a handful of the many use cases where fingerprinting can uniquely identify devices, even as other methods fail.

How the demo works - read MORE on the link above...

What is letterboxing, and can it prevent browser fingerprinting?

Letterboxing DEMOhttps://www.jurajuhlar.eu/letterbox

Letterboxing is a browser feature that adds gray bars around the web view to hide your browser dimensions. It has been available in Tor since 2015 and made its way to Firefox in 2019. As users become more concerned about advertisers tracking their browsing habits, browsers are adopting more privacy features and anti-fingerprinting techniques, including letterboxing. 

This article will explain how letterboxing works, how to enable it, what your window size reveals about you, and whether hiding it can prevent fingerprinting....

Thank you ! Do you know a solid, trusted extension that has an auto setting to delete cookies upon each exit ?

In the Chrome Settings, under "Clear browsing data", right-click on "Clear data" button, then "Add to bookmark"... and use this bookmark link to clean your data... the most simple but efficace solution I've found for you...

- If your browser allows you to do so. It is possible in DCBrowser, but NOT in MiniBrowser, unfortunately.

So in which browser would you like to do this?

...and these two extensions cleaning cookies automatically at browser's exit (but no history, no images...), that I've checked: 

Site Bleacherhttps://chrome.google.com/webstore/detail/site-bleacher/mlcfcepfmnjphcdkfbfgokkjodlkmemo?hl=en-US

Cookie AutoClearhttps://chrome.google.com/webstore/detail/cookie-autoclear/bdlecjncfafhlnehekghapanflfcbikk?hl=en-US - Size 16.13 KiB only...
