Connect it to your Blocky

Browser blocking starts enabled and works independently of DNS. Open the popup's Connection settings and save your Blocky overview address:

http://127.0.0.1

Use the overview address, not the authenticated port 9999 admin site. The address is not applied automatically to an installed extension.

Use Allow site if a page breaks, then reload it. Exceptions cover that exact hostname, not all subdomains. DNS blocking and other extensions may still block requests.

Downloads, privacy & installation limits

There is no telemetry, remote rule download, or automatic system-DNS configuration. The browser applies 48 bundled and your custom third-party domain rules locally. Broad HTTP/HTTPS access supports website exceptions and health checks to your chosen server.

Developer-mode installation may be restricted by your organization or unsupported on mobile browsers. This page does not bypass browser policy, signing, or consent. ZIP downloads are not installed extensions.

Download package versions and SHA-256 hashes. Hashes help detect corruption; they do not authenticate the publisher.

If a package is missing, the server administrator must run the extension packaging command and redeploy Blocky.
