Firefox Monitor is a free service from Mozilla that notifies users when their email has been part of a breach. Hundreds of thousands of users have signed up for this service. Mozilla is now offering Monitor in over 26 languages so that more people can use the service in their native language. It has also introduced Firefox Monitor Notifications to inform users if they have visited a website which was recently breached.
This feature is available exclusively for Firefox browser users. The notification will be shown to Firefox Quantum users on desktop if they visit a website which has recently reported a data breach.
Firefox Quantum users will get a notification when they land on a site that has recently been breached. They can click on the alert to visit Firefox Monitor and scan their email to see whether or not they were involved in that breach. This alert will be shown at most once per site and only for data breaches that have been reported in the previous 12 months.
This functionality is being added to Mozilla’s browser as users become more aware and demanding of these kinds of privacy and security features. Mozilla will be rolling out this feature gradually to Firefox users over the next few weeks.
