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

For entertainment purposes only. Does not do anything in both Chrome and Edge. My GPU and CPU fingerprint remains visible. No tweaking either. Don't waste your time with this.

Не работает
"Cannot support<...>Browser extensions that modify the browser's User-Agent value or Web APIs such as Canvas and WebGL." (https://developers.cloudflare.com/cloudflare-challenges/concepts/how-challenges-work/) Still 5 stars because it's not the fault of the extension.
lately it interferes with the cloudflare human verification, meaning you remain stuck there and the website no longer loads
Добавьте режим который меняет finterprint при перезапуске браузера, то есть fingerprint остаётся всегда один на все сайты пока не перезапустишь браузер
doesnt work; only pretends to work
It is not really that great. It changes your fingerprint, so you have a second one. It does not randomize it.
