Canvas Blocker (Fingerprint Protect)
extension manipulates two methods of HTML5 Canvas element that are commonly used to generate a unique fingerprint key for your browser. This extension slightly perturbs the actual image data only when these methods are called to prevent websites from generating this unique key. Whenever a suspicious method is called the extension notifies the user by displaying a desktop notification. Note that this extension uses non-persistent background page to have no effect on user browsing experience while it is not used. Also compared to other similar extensions, it uses a much faster and more optimized code to prevent fingerprints originated from the Canvas element.
