Description

Canvas Fingerprint Defender is a lite extension that lets you easily hide your real canvas fingerprint by reporting a random fake value. According to many tech blogs, completely blocking canvas fingerprints is not a good idea, therefore reporting a "fake" fingerprint could be the best solution to better protect your privacy. This addon simply adds a small noise to the actual fingerprint and "renews" it every time you visit a website or reload a page. It is important to note that, it does not have any settings or options to adjust. Simply add it to your browser and start surfacing the internet. If you want to test this addon, please visit a website that shows your fingerprint (i.e. browserleaks). Every time you reload the page, you will see a new fake fingerprint. To report bugs, please visit the addon's homepage (https://mybrowseraddon.com/canvas-defender.html) and fill out the bug report form.

Protecting you from fingerprinting? Your browser has a unique fingerprint That is why I installed this to prevent that. Uninstalled.

I spent TWO DAYS debugging my project because of this extension! Every image I drew on a canvas it was getting random colour tints. I was about to throw my pc out the window. Turns out, Canvas Fingerprint Defender was the cause of the issue. Disabled it, and poof - problem solved. This extension might be fine for privacy, but the side effects should be mentioned clearly. Save yourself the headache and disable it while coding.

Don't be mislead by the sophist comments! Despite an "update" in April 2023, this date doesn't represent an update. It means Google's terms have been updated. Check your old version and the latest, it'll be the same. This extension doesn't do anything. Don't let the sophists mislead you further. I confirmed with many different fingerprinting sites . To elaborate further, CFD doesn't prevent sites from knowing what extensions I have, CPU I'm using, RAM, GPU, speakers, etc. Basically all the characteristics a browser leaks without anti-fingerprinting. Furthermore, this extension is abandoned and it simply doesn't work. Full stop. Sadly, the only working extension has now been infected with malware and adware. It took Google more than 3 months to finally remove it after an overwhelming number of flags/complaints. If you want anti-fingerprinting, considering using another browser like Brave or modified Firefox.

It doesn't work. https://coveryourtracks.eff.org/ still detects my unique fingerprint when it's used.

If you are using Brave browser like I am this does more harm than good. Brave (and lots of other browsers) has built in randomization, so adding an extension just makes your fingerprint stand out. If you are unsure, you can test your results at coveryourtracks.com

As much as I think it is good idea, it has been preventing many websites from working properly.

It's not cutomizable at all and doesn't work for classical canvas tracking https://fingerprintjs.com/demo Uninstalled, doesnt do its job but it's free I can't blame, I'll review this later

I had high hopes, since I saw the popups appearing during the Panopticlick scan. Yet at the end I had the disappointment: Does your browser protect from fingerprinting? ✗ your browser has a unique fingerprint

Got problems using this extension while visiting websites under CloudFlare protection: infinite loop of "Verifying if you are human or not".

It seems like this only works against some trackers; I get random fingerprints on https://coveryourtracks.eff.org/ or https://browserleaks.com/canvas, but I don't get them on https://fingerprintjs.com/demo/ (an actual, paid product for this service).

It's great at what it does. And I was shocked to see just how many sites are using browser fingerprinting of one sort or another. But it really needs some configuration options. You can't even turn it on and off from the menubar if it breaks a site. You've got to actually open your browser's preferences and disable it, which is about as user-unfriendly as you can get.
