Defending against Canvas fingerprinting by reporting a fake value.

Download

Features & Capabilities

Canvas Fingerprint Defender is a lightweight Chrome extension designed to enhance your online privacy by spoofing canvas fingerprints. Unlike blocking canvas fingerprinting outright, this extension reports a random fake fingerprint value, adding a subtle noise to your actual fingerprint. It refreshes this fake fingerprint with every page reload or website visit, making it harder for trackers to uniquely identify your browser.

The extension operates seamlessly without any settings or configurations—just install it and start browsing. To verify its effectiveness, you can visit fingerprint test sites like BrowserLeaks and observe the changing canvas fingerprint with each refresh. This approach balances privacy protection with functional web compatibility, providing a smart defense against canvas fingerprint tracking.

User Reviews

Canvas Fingerprint Defender is praised for being a simple, lightweight, targeted protection against canvas fingerprinting and is verifiable with independent testers. However, it often clashes with Cloudflare-protected sites, causing access issues and page breakage. Its effectiveness varies by site and browser, with some fingerprints still appearing on tests. Users note better results on some platforms but not universally. Overall, it’s a low-overhead privacy tool that works well for some setups but can cause compatibility problems on others.

Pros

Effectively blocks canvas fingerprinting and enhances privacy.
Easy to use and lightweight with a low memory footprint.
Focused anti-fingerprinting approach (one-exploit fix) rather than broad spoofing.
Can be validated with external fingerprinting testers (e.g., CoverYourTracks, BrowserLeaks, AmIUnique).
Generally praised as a simple, straightforward privacy tool that works for many users.

Cons

Significant Cloudflare compatibility issues: access blocks, captcha loops, and repeated verification demands.
Site compatibility problems: many websites load incorrectly or stop working with the extension active.
Inconsistent effectiveness across sites and browsers: fingerprint changes are not universal and results vary by tester site.
Brave and some other browsers may experience reduced benefit or adverse effects due to built-in anti-fingerprinting features.
Not all users experience benefits; several reviews report no noticeable changes or limited impact on certain tests.

Recent reviews

I have to disable this extension to pass Cloudflare captcha. Besides that it works well.

Ставлю 5 балов, т.к. давно мне служило верой и правдой. Клаудфларе перестал пускать на 16.12.2025.

Is Canvas Fingerprint Defender Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Canvas Fingerprint Defender requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.
