ChromeGuard

Browser security & privacy hardening — simple for everyone, powerful for experts.

ChromeGuard locks down your browser's security and privacy settings in one click — or lets you fine-tune every detail yourself. Install it and forget about it, or open the full settings page to configure exactly what you want. Secure Browsing - Force HTTPS on all connections - Encrypt DNS lookups with your choice of provider (AdGuard, Cloudflare, Quad9, Mullvad, dns0.eu) - Block annoying notification popups Privacy Protection - Block third-party tracking cookies - Disable Chrome's ad tracking APIs (Topics, FLEDGE, ad measurement) - Send the Global Privacy Control (GPC) signal to every site - Prevent WebRTC from leaking your real IP address Link Protection - Hover over shortened links (bit.ly, t.co, etc.) to see where they actually go - Automatically strip tracking parameters (utm_source, fbclid, gclid) from URLs - Remove click-tracking redirects from Google and Facebook search results Cookie & Storage Cleanup - Automatically delete cookies from sites you haven't visited recently - Clear cookies when you close a tab, with smart login detection to keep you signed in - Remove first-party analytics cookies (_ga, _fbp, etc.) and clear stale site storage - Allowlist domains you want to protect from cleanup Health Monitor - Scans your installed extensions and flags risky permission combinations - Reviews which sites have access to your camera, microphone, and location Environment Detection - Detects active VPNs, DNS software, and ad blockers — including desktop apps like AdGuard and Pi-hole - Shows live status in the popup so you know what's already covered Two interfaces, one extension The popup gives you a simple dashboard with category toggles. The full settings page gives you individual control over every feature, with sidebar navigation and a light/dark/system theme picker. Zero dependencies. Open source. No data ever leaves your browser.
