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.
Browserabdruck - Durchblickt
Nimm deine digitale Souveränität selbst in die Hand, indem dir transparent Tracking Methoden angezeigt werden. Diese Erweiterung informiert praxisnah was ein Browserabdruck (english: browser fingerprint) ist, und zeigt an, ob die aktuell besuchte Webseite einen Abdruck erstellt. Über einem Popup wird angezeigt, ob ein Canvas, WebGL oder Audio Abdruck erfasst wurde. Zusätzlich wird noch die Verwendung von Sensor, Akkustand und Standort Tracking angezeigt. Canvas-, WebGL-, und Audiofingerprinting kann auf https://coveryourtracks.eff.org/ getestet werden. Die Sensorfunktionalität kann auf https://codepen.io/bantic/pen/qbxgBd oder https://sensor-js.xyz/demo.html getestet werden. Es könnte ein Force Refresh (STRG+F5) nötig sein. GPS kann auf https://html5.komplett.cc/code/chap_geolocation/simple.html oder https://www.w3schools.com/html/html5_geolocation.asp getestet werden. Akkustand kann auf https://pazguille.github.io/demo-battery-api/ oder https://googlechrome.github.io/samples/battery-status/ getestet werden. Warnung: Ich empfehle nicht, dieses Add-on dauerhaft zu installieren. Es hat sich gezeigt, dass eine Website theoretisch einen Fingerabdruck der Add-ons erstellen kann, die ein Benutzer installiert hat, indem sie die Skripte überprüft, die im globalen JavaScript-Namespace werden (dieses Add-on führt eigenen Code im Namespace aus, was für Add-ons üblich ist). Durch die dauerhafte Installation dieses Add-ons könnte eine aggressive Anti-Datenschutz-Website eine zusätzliche Kennung zu Ihrer Online-Identität erhalten. Verwenden Sie es nur zu Informations- und Forschungszwecken :)
Canvas Blocker - Fingerprint Protect
This browser extension safeguards user privacy by preventing malicious scripts from using the HTML canvas element for user fingerprinting. It introduces slight changes to the data generated by the canvas element when specific methods are invoked, rendering it unusable for fingerprinting. In comparison to similar extensions, this one is lighter and employs a more efficient method to obstruct fingerprinting across all frame elements (top and subframes). The extension operates in three modes: 1. Random noise 2. Random noise (per page) to maintain a consistent identity within the current page session 3. Fixed noise to sustain a constant yet unique identity continuously Key Features: 1. Minimal footprint fingerprint defender 2. Ability to block or disable fingerprinting on specific hostnames 3. Notification when canvas fingerprinting is detected 4. Option to disable notification for select or all hostnames 5. Compatibility with cross-origin (CORS) and sandboxed iframes (such as Disqus and Hangouts) Notes: This extension doesn't entirely block the canvas element. Instead, it modifies two methods to prevent the JavaScript engine from creating a unique identification key from this element. What is Canvas Fingerprinting: Canvas fingerprinting is a method among several browser fingerprinting techniques used for tracking online users. It enables websites to identify and monitor visitors by leveraging the HTML5 canvas element rather than browser cookies or similar means. This technique functions by exploiting the HTML5 canvas element. When a user visits a webpage, the fingerprinting script initially writes text using the preferred font and size and adds background colors. Subsequently, the script calls the Canvas API's ToDataURL method to retrieve canvas pixel data in dataURL format, essentially a Base64 encoded representation of binary pixel data. Lastly, the script hashes the text-encoded pixel data, creating a unique fingerprint.
Fingerprint Protector
Professional anti-fingerprinting: DNR Client Hints, MAIN-world spoofing, iframes, site rules, and tracker blocking. Fingerprint Protector helps you reduce cross-site browser fingerprinting—the technique websites and trackers use to recognize you without cookies. HOW IT WORKS • Injects privacy protection early on every page load (including iframes) • Uses a stable, seed-based virtual identity so your spoofed profile stays consistent across tabs • Rewrites HTTP Client Hints (User-Agent, Sec-CH-UA*) at the network layer to match your profile • Optional blocking of known fingerprinting CDN hosts KEY FEATURES • Protection presets: Balanced, Maximum, Paranoid, Compatible • Per-site rules: relaxed mode for video calls, or disable on specific sites • Privacy score (0–100) with tips in the toolbar popup • Modules: Canvas, WebGL, Audio, fonts, screen, timezone, media devices, speech, battery, performance, ClientRects, Permissions API, hardware APIs, Privacy Sandbox signals • Right-click menu for quick site exceptions • Keyboard shortcut to toggle protection (Alt+Shift+F) • Local audit log and JSON export/import of settings • Built-in relaxed rules for Google Meet, Teams, Zoom, Discord, and more PRIVACY FIRST All processing happens on your device.
