LibreGuard bởi LibreSearch

How it works
LibreGuard blocks ads, trackers, and malicious domains at the network layer using Chrome and Firefox's declarativeNetRequest API. Requests are intercepted before they ever leave your browser — no JavaScript injection, no slow per-request processing, no data collection.
At build time, LibreGuard compiles 300,000+ domains from trusted, community-maintained filter lists into efficient static rules that ship with the extension.
