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.

Latest reviews
- (2025-06-04) Colour setm: 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?
- (2025-05-02) username: 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 :(
- (2024-12-05) fahim rahman: 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.
- (2024-11-01) عادل قسيس: 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)
- (2024-10-05) Emre Özdurna: 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
- (2024-09-02) Pilot Man: 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
- (2024-08-14) Gavaboi fpoluit: 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
- (2024-07-30) Robin Luo: 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.
