Protect your browser from fingerprint tracking and data leaks. Spoof canvas, WebGL, audio, and more. Stop websites from tracking you through browser fingerprinting. This extension masks your digital fingerprint to protect your online privacy. ✓ Canvas Fingerprint - Adds noise to prevent canvas-based tracking ✓ WebGL Fingerprint - Spoofs GPU vendor and renderer strings ✓ Audio Fingerprint - Masks audio context fingerprinting ✓ Navigator Properties - Platform, hardware, language, and more ✓ Screen Resolution - Spoofs screen and window dimensions ✓ Client Hints - Masks User-Agent Client Hints API ✓ WebRTC Protection - Prevents IP leaks through WebRTC ✓ Timezone Spoofing - Masks your local timezone ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🌐 WHY YOU NEED THIS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Websites collect hundreds of data points about your browser to create a unique "fingerprint" that can track you across the web - even without cookies. This includes your screen size, installed fonts, graphics card, and more. Fingerprint Shield makes your browser look like millions of others, protecting your privacy while browsing.
CthulhuJs (Anti-Fingerprint)
Your browser, your rules — your digital fingerprint, in your control. 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.
FINGER
This tool was developed by security experts after a deep research, it's ready to block the most trend and sofisticated trackers. 🧿🌐FINGER – Live‑Time Browser Fingerprinting Shield Protect your privacy at its deepest layer. ➡️ FINGER is a powerful Chrome extension designed to detect and block browser fingerprinting as it happens. Instead of relying on outdated blocklists, FINGER monitors actual behavior inside the browser—catching hidden tracking scripts that other tools miss. Why Choose FINGER? Browser fingerprinting allows websites to identify you by collecting subtle details about your device—even with cookies disabled. Most privacy tools never look at this layer of tracking. FINGER changes that by offering: 🛡️ Live-Time Protection Blocks fingerprinting attempts the moment they occur—before any identifying data leaves your browser. 🧠 Behavior-Based Detection Finds fingerprinting scripts even when they’re obfuscated, dynamically injected, or designed to evade filter lists. 📊 Entropy Insights Each attempt is analyzed and scored with an approximate entropy value, giving you visibility into how “unique” you appear. 🔒 100% Local & Private All analysis happens directly in your browser. No data is ever sent anywhere. 🔧 Minimal Permissions Uses only what’s necessary (ActiveTab), reducing risk and aligning with best security practices. 🧩 Modular, Extensible Architecture Easily add new detection or blocking rules—perfect for advanced users and researchers. 💻 Open Source Community-driven, transparent, and available under the MIT license. Key Features ⚡🔴 Live Fingerprinting Detection Instantly see when a website tries to gather identifying metrics. ⚡🕵 Comprehensive JavaScript Interception Monitors method calls, property access, and API usage linked to fingerprinting. ⚡📟 Clean, Intuitive Dashboard View logs, entropy scores, and blocked attempts with ease. ⚡🎓 Research-Grade Toolkit Built for privacy enthusiasts, academics, and developers auditing web applications. ⚡🔜 Future-Proof Design Ready for upcoming enhancements, including iframe inspection and cross-browser support. Who Is FINGER For? 👤 Privacy-Conscious Users Block invisible tracking while browsing. 👨🏻🏫 Researchers & Educators Study real-world fingerprinting techniques in controlled environments. 🙍🏻♂️ Web Developers Audit your own sites for accidental or legacy fingerprinting logic. 👩🏼💻 Open-Source Contributors Improve detection modules, extend coverage, and help the community grow. How FINGER Works ➡️FINGER uses advanced JavaScript interception techniques, including: 🪖 Method Overriding ⛊ Property Redefinition 🤺Proxy Wrapping for Dynamic Objects These techniques allow precise, live-time blocking without degrading your browsing experience. How FINGER Compares ➡️ Tools like AdBlock Plus, uBlock Origin, Privacy Badger, and Disconnect rely on static filter lists. FINGER complements them by targeting behavioural fingerprinting, a type of tracking most extensions do not inspect. 🔜 Future Roadmap 🌕Enhanced iframe and embedded context detection. 🔭Cross-browser compatibility (Firefox, Edge, Safari). .𖥔 ݁ ˖ִ🛸༄˖°. Configurable user policy engine for custom blocking strategies. 🚀Integration with research platforms for large-scale studies. Changelog v1.2.1 — Adjusted action height to 100% to ensure all content is fully visible. v1.2.2 — Fix: Preserve original constructor prototype when wrapping constructors to avoid breaking built-ins. v1.2.3 — Restore native Uint8Array via Reflect.construct to preserve original constructors/symbols and prevent uncaught TypeErrors. v1.2.4 — Fix: Ensure Node.prototype.appendChild is intercepted instead of HTMLElement.prototype.appendChild to maintain correct prototype chain behavior and prevent breaking DOM operations in complex SPAs (e.g., Jira). v1.2.5 — Fix: Corrected a conditional logic error in the entropy calculation that was preventing accurate results. Updated the “Send your feedback” action to redirect users to GitHub Issues.
Browser Fingerprint Shuffler
It helps users evade precise anti-sybil detection from websites by adding persistent, low-level noise to browser fingerprints. Protects against browser fingerprinting by adding deterministic noise to fingerprinting APIs
WebGL Fingerprint Defender
WebGL Fingerprint Defender is a browser extension that let you easily hide your real WebGL fingerprint by reporting a random fake value. According to many tech blogs, completely blocking WebGL API is not a good idea, therefore reporting a fake fingerprint could be the best solution to better protect your privacy. This add-on simply adds a small noise to the actual fingerprint and renews it every time you visit a website or reload a page. With the browser's WebGL API, in general, two types of fingerprints can be generated. One with WebGL constants and the other with an image that is rendered with the WebGL API. This add-on can spoof both values at the same time. To disable this add-on, please visit the extensions page in your browser and then click on the disable button. Please note that this add-on does not have any toolbar icon/button. This extension is made in collaboration with the author of "Canvas Fingerprint Defender": https://chrome.google.com/webstore/detail/canvas-fingerprint-defend/lanfdkkpgfjfdikkncbnojekcppdebfp If you have a feature request or found a bug to report, please fill out the bug report form on the add-on's homepage (https://mybrowseraddon.com/webgl-defender.html).
