Prevent HTML canvas element from generating a unique identification key to protect user's privacy
a simple option-less extension to prevent the canvas element from being used by malicious scripts for fingerprinting a user. This extension adds a slight noise to the data generated by canvas element when certain methods are being called. This way the canvas element cannot be used for fingerprinting purposes. Compared to other similar extensions, this one is lighter and uses a more effective method to block fingerprinting from all frame elements (top and subframes). Notes: 1. There is no on and off button as the extension is not meant to be disabled. If there is a use case of the on and off button please report on the FAQs page (review section) 2. This extension does not block canvas element entirely. It only modifies two methods to prevent JS engine from generating a unique identification key from this element.
- (2020-02-03) Clemens Ratte-Polle: fine :) But what about an option for disabling Canvas Blocker (Fingerprint Protect) on some sites?
- (2020-01-30) ポール: Confirmed to work and has a whitelist - perfect! Also very light weight.
- (2019-09-20) Cunninghams Law: The notifications are driving me nuts. How to disable?
- (2019-08-31) A B: This should have a one click button to turn off notifications
- (2019-03-10) Amardeep Verma: 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.
