Description

CthulhuJs Is A Browser Fingerprint Obfuscation Extension This browser extension aims to enhance user privacy and security by disguising browser fingerprints, protecting users from tracking and identification. Here are its key features: Multiple Fingerprint Obfuscation Techniques: It supports obfuscating various browser fingerprints, including canvas, audio, webgl, webgpu, fonts, plugins, clientRect, webrtc, language, timezone, screen, gpu, memoryCapacity, processors, and useragent. Dynamic Random Fingerprint Generation: Based on network information and user configuration, it dynamically generates random fingerprints, making them harder to identify. Flexible Fingerprint Switching Strategies: Users can choose different fingerprint switching strategies, such as time intervals, page load counts, or custom rules. Tab-Level Fingerprinting: Each tab can use a different fingerprint, enhancing privacy protection. Persistent Fingerprint Configuration: Fingerprint settings persist across sessions without any limitations. This browser extension helps users better safeguard their privacy, preventing tracking by advertisers, analytics tools, and other trackers. If you’re interested, you can search for and install it from the browser extension store.

Cover Your Tracks says that my fingerprint is unique. It isnt randomized since if it was it would say that there.

This extension is not doing well at all, I want you to switch this extension to be like "Canvas Blocker" extension on firefox and on this way, your extension will be the best fingerprint blocker on the chrome web store and firefox (if will pushed this extension there)

Full of bugs settings not saving. random generator always showing same confing everytime and when u change it manually it will back to default again and also your fingerprint sometimes not hide if developers fix this issue it will become one of the strongest anti-fingerprints tools for chrome

1. if refresh 10/15 max browserleaks canvas pages, it will fail atleast 1/3 times. 2. client-hints are not accurate. 3. failed spoofing at worker level detection like CreepJS
