CthulhuJs (Anti-Fingerprint)

Generate a new fingerprint with one click, and each window can be a different browser

CthulhuJs - Advanced Anti-Fingerprint Extension

CthulhuJs (Anti-Fingerprint) is a browser extension designed to enhance user privacy by obfuscating browser fingerprints. It employs multiple techniques to mask information such as canvas, audio, and user agent, making tracking more difficult. Users can dynamically generate random fingerprints, utilize varying switching strategies, and have a unique fingerprint per tab. This allows for better control over online identity and protection against tracking by advertisers and analytics.

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.
