“It’s easy to feel powerless when you hear about data breaches and not knowing if you’ve been personally affected,” Cindy Hsiang, a product manager at Mozilla, said in a video announcing Firefox Monitor. “Firefox Monitor tells you where your accounts were compromised, so make sure you change your password wherever you’ve used it.”
The service will also allow users to sign up to hear about future data breaches by scanning an email address. The company said it will alert users of a breach in a private email.
The company has made a number of user security enhancements in recent weeks.
Earlier this month Mozilla announced that it planned to block user tracking data on websites by default in its Firefox browsers. The company said this will improve page loading speeds, remove cross-site tracking, and help prevent “harmful practices” like collecting identifiable data on internet users.
