            <p>
                The button above will run a port-scan of your local network. It works by triggering HTTP <code>GET</code> requests via
                a hidden image's <code>src</code> attribute. The port-scan results will <em>never</em> be uploaded to remote servers and will
                never leave your computer. You can verify this and fully monitor the scan from the <a href="https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/index.html" target="_blank">DevTools Network tab</a>,
                or check on the list of the local domains scanned below.
            </p>
            <p>
                To protect against private network port-scans like these there are several options:
                the <a href="https://addons.mozilla.org/firefox/addon/port-authority/">Port Authority browser addon</a> is designed specifically to block private network port-scans.
                Alternatively, <a href="https://addons.mozilla.org/firefox/addon/ublock-origin/" target="_blank">uBlock Origin</a> users
                can add the <a href="https://github.com/gorhill/uBlock/wiki/Dashboard:-Filter-lists#block-outsider-intrusion-into-lan" target="_blank">"Block Outsider Intrusion into LAN"</a> filter list.
