Your right to be safe from hackers starts here.

Firefox Monitor warns you if your email address has been exposed in an online data breach. See if your information has been exposed, learn how to better protect your online accounts, and get alerted if your email address appears in a new breach.

How Firefox Monitor works

Conduct a basic search

Search for your email address in public data breaches going back to 2007. This basic search will surface most data breaches, but not ones that contain sensitive personal information.

Search Your Email

Sign up for breach monitoring

Create a Firefox Account to monitor your email for ongoing breaches. Once you’ve verified your email, you’ll also receive a full report of past breaches, including sensitive breaches.

Get notifications in your browser

If you use Firefox, you’ll receive a notification if you visit a site that’s been breached. Find out right away if you were part of that breach and what you can do about it.
