ChromeJShelter
By: jshelterdevs
Protect your browser from fingerprinting and malicious JavaScript. JShelter controls and restricts browser APIs to reduce tracking and data leaks.
Features & Capabilities
JShelter is a browser extension that returns control over JavaScript-driven behavior to the user. Acting like a firewall for browser APIs, it lets you allow, block, or restrict access to sensitive browser capabilities to prevent fingerprinting, tracking, and unwanted data leakage. JShelter can also reduce precision for features like geolocation and apply safeguards against attacks targeting the browser, OS, or hardware. Beyond blocking, JShelter helps you learn how pages call JavaScript APIs with its Fingerprint Detector and exportable JSON reports. The project provides documentation, a threat model, and a research paper for deeper understanding (see the FAQ and blog on jshelter.org and the arXiv paper). Use JShelter to harden your browsing privacy and security while retaining per-site control over what web pages can access.
