Overview
Product summary
Review the store description, core capabilities, and common use cases.
This browser extension safeguards user privacy by preventing malicious scripts from using the HTML canvas element for user fingerprinting. It introduces slight changes to the data generated by the canvas element when specific methods are invoked, rendering it unusable for fingerprinting. In comparison to similar extensions, this one is lighter and employs a more efficient method to obstruct fingerprinting across all frame elements (top and subframes). The extension operates in three modes:
1. Random noise
2. Random noise (per page) to maintain a consistent identity within the current page session
3. Fixed noise to sustain a constant yet unique identity continuously
Key Features:
1. Minimal footprint fingerprint defender

RE: the comment about https://browserleaks.com/canvas, if you refresh the page, you will see this extension causes the canvas to generate a unique fingerprint each time you visit the page, compared to the same fingerprint every time with the extension disabled.

fine :) But what about an option for disabling Canvas Blocker (Fingerprint Protect) on some sites?
Confirmed to work and has a whitelist - perfect! Also very light weight.
The notifications are driving me nuts. How to disable?
This should have a one click button to turn off notifications
This Fingerprint canvas blocker does not block most of the websites. For example in Firefox there is a CanvasBlocker extension which blocks canvas fingerprinting on many sites which this extension misses. Further there is no visual indicator when a website is blocked from carrying out Fingerprint blocking.
Is it possible to disable the notifications just for this plugin? I don't want to disable notifications all out for chrome - I just don't want to see them for this
Works Great! I have been using it for a few months now and no problems. Nice and fast, keep providing future updates to this extension.
