Description

WebGL Fingerprint Defender is a browser extension that let you easily hide your real WebGL fingerprint by reporting a random fake value. According to many tech blogs, completely blocking WebGL API is not a good idea, therefore reporting a fake fingerprint could be the best solution to better protect your privacy. This add-on simply adds a small noise to the actual fingerprint and renews it every time you visit a website or reload a page. With the browser's WebGL API, in general, two types of fingerprints can be generated. One with WebGL constants and the other with an image that is rendered with the WebGL API. This add-on can spoof both values at the same time. To disable this add-on, please visit the extensions page in your browser and then click on the disable button. Please note that this add-on does not have any toolbar icon/button. This extension is made in collaboration with the author of "Canvas Fingerprint Defender": https://chrome.google.com/webstore/detail/canvas-fingerprint-defend/lanfdkkpgfjfdikkncbnojekcppdebfp If you have a feature request or found a bug to report, please fill out the bug report form on the add-on's homepage (https://mybrowseraddon.com/webgl-defender.html).

Absolutely useless. Even while it says my fingerprint is randomized, I'm on browserleaks seeing that it's not

Not amused getting https://mybrowseraddon.com/webgl-defender.html?v=0.1.6&p=0.1.5&type=update every time I launch my browser now. Never use to get it. It never finishes loading. I've tried to go to their bug site but all I get is that page again. I really need this fixed.

https://webbrowsertools.com/webgl-fingerprint. This website is still able to detect wheather we are spoofing WebGL Fingerprint or not so now what is the benefit of using it?

Won't work. It's trivial for a site to know you're using this plugin. Hence you are fingerprinted. You've merely replaced your WEBGL-fingerprint with a WEBGL-blocker-fingerprint. If the fingerprint spoofing was undetectable, that might work.

Enabling this plugin will prevent embedded flowcharts in Lark doc documents from opening.

I mostly use this extension in my primary browser, Opera (as Opera is on the Blink engine, which is based on Chromium, it can install Chrome extensions) and boy could it really use some options. I realize I'm posting this as a review for the both Chrome & Opera, but many of the criticisms still apply to both. Firstly, when I went to install this extension in Chrome (to write this review) I got an error that popped up from Google that said "This extension is not trusted by Enhanced Safe Browsing" and gave me a link to learn more which sent me here: https://support.google.com/chrome_webstore/answer/2664769 Second, my god the notifications and sounds. In Chrome I assume you can disable this. In Opera, unfortunately you cannot. So, the constant popups and beeping gets OUTRAGEOUS on some websites I visit. I filed a bug report on this with the author of the plugin but still haven't heard back. Third, this should be optionally combined with the author's other plugins - Canvas Fingerprint Defender, Font Fingerprint Defender, & Audiocontext Fingerprint Defender. The author makes another plugin I use called Privacy Tweaks I use as well, because it has optional geolocation blocking and spits out a random timezone to the websites you're visiting. Besides that, it's a pretty standard ad + tracker blocker. I don't know why he can't make another optional "defender" type plugin that would defend against all that other stuff without separating them. If anyone knows one that blocks all these, please let me know in the comments below. The author has separate extensions for geoblocking and timezone switching, so I don't know why he couldn't combine all these defender plugins into one single extension. Fourth, yes, as many people have mentioned, this - and the other defender plugins need a pause/disable button and a whitelist. That should be standard for any kind of extension of this type. Any kind of privacy extensions that blank block content on all websites is simply not acceptable. Some websites just won't operate if you're blocking this type of content and so a whitelist is MANDATORY! Otherwise you have to go into extensions, disable it, do your surfing, then go back and turn it back on. Finally, sites CAN detect this as a spoofed WebGL value, as opposed to a fake one. When you click on the extension under your extension tabs or the icon you have pinned and choose "What's my fingerprint?" It takes you to this website: https://webbrowsertools.com/webgl-fingerprint/ where the value for "Is browser webgl fingerprint spoofed" reads "true". Ideally, this would read "false" as it would send fake WebGL packet to the server and not come back detecting it as spoofed, making your browser look suspicious in the eyes of some web hosts.

It use to work. But now doileak(.com) can detect IP with this app enabled. I have ran this for over a year without issue. So the newest detection software see's through it. Removed from chrome and using other options. Use to work great, just zero updates and zero support.

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.

On the https://browserleaks.com/webgl time to time a real "WebGL Image Hash" is shown, although the extension notifies of a fake. Same thing on https://webbrowsertools.com/webgl-fingerprint/ . From time to time the same one appears "Fingerprint ID Method: red solid box".
