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.

Canvas一直被检测到，怎么解决？
10/10 Worked like a charm—capable of randomizing hardware context fingerprinting, canvas fingerprinting, and all other factors (as advertised). I haven't found a single alternative which goes as deep as this one. I believe many of the negative reviews stem from people expecting this to work as a plug-and-play extension. So, I’d suggest enabling randomization by default. This would prevent inexperienced users from getting confused and assuming the extension doesn’t work, which seems to be the case here with the negative reviews. Given Google's recent changes in their policy regarding digital fingerprinting, this extension needs to be widespread now more than ever! Much appreciation to the dev <3 ps: For some reason it doesn't seem to work at all on Arc Browser :(
extension is great, but it will better if random genarated option will be selected by default, otherwise i need setup those settings every time after install the extension.
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)
大佬。这个插件很好用，有一个问题，随机了一些UA等信息，更换代理后时区信息需要自己点击更新网络。如果切换了代理，时区显示还是上一个ip的时区，这个有办法自动获取吗？ 感谢大佬
Hello, my friend. I really liked your extension; great job, well done! However, I have a request. I'm using this extension with Chromium Driver and loading it by showing the path to the folder. But for my bot, these settings need to be applied automatically. Is it possible to do this according to a random fingerprint dataset instead of manually setting it or through a popup? I want it to work automatically as soon as the extension is loaded. If you could help me with this, you can contact me on Telegram: DosCode
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
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
When i used it, open youtube, it can't open the video, and tips: Something went wrong. Please try again later. 282054944 what's the problem.
Very, very good
