Breach alerts in the address bar privacy panel
Firefox shows a breach warning in the address bar’s trust panel when you visit a site that has appeared in a known data breach.
Not enabled in Waterfox
Waterfox ships the address bar trust panel, but with breach alerts off and locked off. The feature requires checking the sites you visit against a Mozilla-hosted breach collection, which means disclosing part of your browsing to a third party.
The preference is browser.urlbar.trustPanel.breachAlerts, and it is locked.
What the trust panel still does
The panel itself is present and useful. Select the icon at the left of the address bar to see:
- Whether the connection is encrypted, and details of the site’s certificate.
- Which tracking protections are active on the page and what was blocked.
- Permissions you have granted the site, such as camera, microphone or location, with controls to revoke them.
- Cookie exceptions for the site.
Everything in that list is computed locally from the page you are already loading. None of it involves sending the site you are visiting to an external service.
Checking for breaches yourself
See Alerts for breached websites for how to check breach data directly, and what to do if a site you use has been breached.
