ConfirmURL browser extension

Check the page you're on, or any link, without leaving the tab.

• Toolbar button - one click checks the current tab and shows the verdict, score and top reasons.
• Right-click a link → Check link with ConfirmURL - opens the full report.
• Link warning badges (optional, off by default) - hover a link for a moment and a small badge shows if it looks risky.

The extension isn't in the Chrome Web Store or Firefox Add-ons yet, so install it by hand:

2. Open chrome://extensions (or edge://extensions).
3. Turn on Developer mode.
4. Click Load unpacked and pick the unzipped folder.
5. Pin ConfirmURL from the puzzle-piece menu.

Firefox

3. Click Load Temporary Add-on and choose manifest.json (temporary add-ons are removed when Firefox restarts).

Privacy

• The extension sends a URL to confirmurl.com only when you ask: clicking the button, using the right-click menu, or hovering a link when badges are turned on.
• Each check is handled like any other check on this site: the URL, your IP address, approximate country and the result are logged for 30 days, visible only to the site owner. See the Privacy Policy.
• It does not read page content, form fields, passwords, cookies or your browsing history, and has no analytics or ads.
• Permissions: activeTab (read the current tab's URL when you click), contextMenus, storage (your settings), and access to confirmurl.com. Link badges ask for permission to run on all sites only when you switch them on.

Store listing: the package is store-ready, but Chrome Web Store / Edge Add-ons / Firefox Add-ons submission has not been done yet.
