Review summary

CanvasBlocker is highly praised for its fingerprinting protection and privacy gains; most reviews cite its ability to change fingerprints on refresh and customizable site-specific settings that keep browsing smooth. It is generally described as lightweight and easy to test. However, a minority report inconsistent results (fingerprints not changing or fingerprint checks indicating no effect) and a few isolated complaints about site breakage on certain services. Overall, it’s viewed as a valuable privacy tool with occasional reliability caveats.

Pros

Changes the fingerprint on every refresh, reducing tracking.
Strong privacy/anti-fingerprinting enhancement; widely appreciated and essential for anonymity.
Per-site customization with adjustable strictness to prevent breakage.
Lightweight, runs in the background and doesn't slow browsing.

Cons

Inconsistent effectiveness; some users report fingerprints don't change or tests show no effect.
