How to Get Data Breach Alerts from Mozilla Firefox Monitor

Data security and privacy are increasingly becoming the main focus for the Mozilla Firefox browser. While Mozilla continues to explore subscription-based services aimed at privacy, such as Mozilla VPN, a number of tools are integrated into the browser for free.

Below, we’ll cover how to use one of Firefox’s built-in security tools: A data breach monitoring service called Firefox Monitor.

What is Firefox Monitor?

Firefox Monitor is a service provided by Mozilla, together with Have I Been Pwned, to monitor whether your data is exposed in an online data breach or not.

The Mozilla Firefox Monitor service takes your email address and scans it from a library of known data breaches to see if you are affected. The scan from Firefox Monitor will look for public data breaches dating back to 2007.

Likewise, you can sign up to be notified if your email address is compromised in the future. Best of all, you don’t actually have to use the Firefox browser to take advantage of Firefox Monitor.

How to Use Firefox Monitor

Getting started with Firefox Monitor is a simple process. To get started, you’ll need to visit the Firefox Monitor website. You will be greeted with an invitation to check your email address for known public data breaches. Please enter an email address.

This can be done in any browser, with any email address.


Once you have submitted your email address, you will immediately receive results showing how much – if any – address-breaking data appears.


Now, from the scan results page, click on the button that says “Notify me of new violations” and you will be prompted to sign in with your Firefox account. Note that you don’t need to use Firefox to register a Firefox account.

Because of this, you’ll need a Firefox account if you want to sign up for advanced monitoring and alerts. This website will guide you in creating it.


Once signed in, you will be directed to a violation summary page telling you how much breach data has been associated with the email account. This page will also confirm how many email addresses are actively monitored for future data breaches.


You will also receive an email report on the email address you have chosen to monitor.


There she is. If the email address you have provided is caught in a data breach, you will be notified. Keep in mind, however, it can take a long time for data breaches to be discovered, verified, and added to public databases.

However, there may be some time lag between when the actual breach occurred and when Firefox Monitor notified you.

Unsubscribe from Firefox Monitor

If you decide you no longer want to be a part of Firefox Monitor, unsubscribing is a fairly easy process. To do so, you will need to visit the Firefox Monitor website, and log in with your Firefox account.

Once logged in, you will see your profile icon in the far right corner of the screen, next to the grid menu icon. Click your profile icon to access the drop-down menu. From the drop-down menu, click “Preferences” to open Firefox Monitor settings.


Here, you’ll see several options on how to receive alerts from Firefox Monitor, as well as an option to add another email address. At the bottom of the page, you will see an option to “Remove Firefox Monitor” which will let you choose not to receive any future emails from Firefox Monitor.


After you click the “Remove Firefox Monitor” button, you will be asked to confirm the choice. After doing so, you will be eliminated and taken back to the Firefox Monitor home page. Your Firefox account will remain active, and you can re-register at any time.
