Firefox Monitor is a service by Firefox maker Mozilla that allows anyone to check whether an email address or username has been part of a data breach. Mozilla launched Firefox Monitor back in 2018 and integrated the service into the Firefox web browser in the same year.
Anyone may open the Firefox Monitor website to check an email address for breaches and to set up the service to receive emails when account information is found in new data leaks.
Users who sign-up using a Firefox Account -- sign-up is free -- get additional features on top of that. One of the latest features that Mozilla added to the service is a resolve option that you may use to mark any breach as resolved; this is useful to keep an overview of breaches.
Resolved in this context means that you have taken countermeasures to invalidate the leaked password, e.g. by changing the password, closing the account or by enabling two-factor authentication if available.
The new option is highlighted on the dashboard currently. When you scroll down on the page and look at any of the services your data leaked from, you find a new option to mark the breach as resolved. Doing so hides the leak from the dashboard and puts a nice progress bar at the top that indicates the issues that you resolved in percent.
Once you’ve taken the steps you can to address this breach, you can mark it as resolved. You can still access details about the breach from your dashboard at any time.
The general handling of leaked passwords does not change. You should change the account password asap and make sure that you have not used the same email and password combination at other sites; if you have, you should change the password on these sites as well and consider setting up two-factor authentication if available.
Password managers like KeePass help you generate secure unique passwords for each service and store everything securely.
The new option to mark breaches as resolved is useful as it helps with keeping an overview of breaches and separating resolved from unresolved data leaks.
