Latest reviews

• (2021-04-18) jbzdarkid: 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).
• (2021-04-14) Travis Hookham: Good privacy app. Wish there were a customizations page.
• (2021-04-01) Антон Пальчиков: как настроить? не работает у меня
• (2021-03-31) Stanton McCandlish: Does exactly what it should do and claims it does. Tested at https://browserleaks.com/canvas I like that this is a one-exploit fix instead of a plugin claiming to spoof all forms of user fingerprinting, since new methods of that come up all the time. It's better to be certain that you have a particular weakness patched up because you have an extension that corresponds to it exactly, than to go without preventing a leak because you assumed it was included in some catchall extension but it wasn't. PS: Anyone who cannot figure out that they can click on the extension's icon and pick "Show|Hide desktop notifications" simply doesn't DESERVE to use this extension. Heh. Really, the developer should just turn this option off by default, since it's obviously the only thing causing unhappy feedback.
• (2021-02-11) Griffin Hadd: Not a lot of options apart from notifications and activation/deactivation but works well. Its not supposed to make your fingerprint not unique but does deceive a lot of sites
• (2021-01-29) anas el: love it
• (2020-12-28) Morris Sasser: It doesn't work. https://coveryourtracks.eff.org/ still detects my unique fingerprint when it's used.
• (2020-11-05) Olivier Marsilius: 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
• (2020-10-21) Айрат Халитов: Скриншоты, сделанные в браузере с этим расширением, получают какой-то цветовой шум (разные оттенки). Лучше загружать фото и делать скрины без него (заранее отключать расширение)
• (2020-10-01) Rainbow Warrior Princess: Good canvas blocker, but still incompatble with, respectively blocks, the ebay identity check (Google recaptcha) when logging in, please fix that.
• (2020-08-27) Alessandro Magni: 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
• (2020-08-16) n ascentt: Does what it claims to. Gives you a different 100% unique fingerprint each time.
• (2020-08-16) tech master: dont work. i tested with uniquemachine.org and it identified me everytime
• (2020-08-03) stíobhart matulevicz: 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.
• (2020-08-03) Chris G. Simmons: Seems to work perfectly. It does need a whitelist for the troublesome sites.
• (2020-04-16) Holy Loren: Please, make canvas changes manually!
• (2020-04-10) Daromir Firunsson: Tut was es soll, hat aber leider keine Whitelist. Manche Funktionen auf Seiten machen oft Probleme, dann muss man das Plugin erst per Hand deaktivieren.
• (2020-03-08) A N: Working. Awesome! Now if I could just randomize the other stuff that websites track.
• (2020-03-07) Lecoin Names: Canvas Fingerprinting is evolving everyday...
• (2019-08-25) cars x: perfect, does what i need it to do, it will randomize your fingerprint across all sites trying to read it. i tested with panopticlick and every time it gave a different fingerprint. this is a great extension for anyone looking for an extra layer of anonymity.
• (2019-07-02) Inderjeet Singh: Works as described. Loved it.
• (2019-04-03) Randy D: I like it
• (2019-03-28) fajin yu: It woks every time I reload the website, it generate different fingerprint.
• (2019-03-02) Awesome, does exactly what I need it to do! Although, I know how to detect this with Javascript, it just takes a little bit of thinking ;-).
• (2018-12-30) Phillip Roth: Works as expected. You should put the repository on GitHub so we can make a settings page to allow customization.
• (2018-12-22) Olivier Pötgen: Funktioniert tatsächlich. Kann man zum Beispiel bei browserleaks.com testen. Bei jedem Refresh der Seite kriegt man ne neuen Fingerabdruck. Hab auch gemerkt, daß gewissen Seiten nicht richtig funktionieren, wenn die Erweiterung läuft. Deswegen wäre es schön, wenn man für gewisse Seite Ausnahmen setzen könnte :)
• (2018-11-19) Hakan Er: Çalışıyor.
• (2018-10-13) Alex Kovar: Seems to work well. Only thing is for panopticlick it seems to break something which makes me a bit wary.
• (2018-08-19) The 33 Coder: The extension doesn't work! I am always unique on test sites...
• (2018-06-30) Moin Morgen: ist ganz nützlich wenn man privater surfen will.
• (2018-04-15) [Taps Canvas Fingerprint Defender icon repeatedly] Hello? Is this thing on? It's just grayed out.
• (2018-03-17) Fedogini A.: Good, but could be better if we have an option to disable the notification.
• (2018-03-10) Kevin: Would like options, and the ability to add the icon to the addon-bar. Other than that, I really like it; it simply works. Big thanks to the developer(s)!
• (2018-02-26) Grégory LE MESTRE: No Popup option please !
• (2018-02-09) G.O.D: So far so good.
