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.

Cover Your Tracks says that my fingerprint is unique. It isnt randomized since if it was it would say that there.
Is there a way to switch to English?
关闭浏览器之后在打开不管策略选随机选择配置还是生成配置都完全无效，只能固定一个配置。刷新标签页也是
Really useful, any plans to release the source code?
非常棒的插件，谢谢大佬，大佬辛苦了
有暴露接口吗，油猴调用更新网络、更换环境 新开页面不会更新随机数？ 更换环境不会自动更新网络？ 一键新机只是清理当前域的信息吧！不会删掉其他东西吧
抖音创作者一打开就一直转圈圈，什么情况啊
I read the privacy policy of this extension, which reads: This extension will collect the user's IP address and other personal information, and will also be shared with third parties from time to time. Is this true? Why do this?
大佬牛逼
测试了一些指纹网站效果确实好.或许是干扰指纹的方法太激进了,一些网站存在兼容问题,目前发现youtube不能播放视频,显示出了点问题。请稍后重试。282054944. bilibili不能加载用户个人空间的内容,开启安全模式也没用,黑白名单无效,打开开关后重新点开插件又会关上,小概率的情况下打开的新页面,插件图标不显示on,点开插件也没有显示配置.
