One more thing is coming to add to the capabilities of the recently released Firefox 57 aka Firefox Quantum.
Mozilla is working on a new feature for Firefox, dubbed Breach Alerts, which will warn users when they visit a website, whether it was hacked in the past or not.
Mozilla has teamed up with the website “Have I Been Pwned” whose data will be used to notify users about any data breaches. This feature is in the works.
Firefox’s new warning system is currently in the early stages of development. It’s unclear how it would work and how far in the past Breach Alerts would go when reporting data breaches to the users.
According to the GitHub repo of the Mozilla engineer working on the Breach Alerts project, the warning notifications will focus more on recent security breaches.
The warning notifications would also carry a “Learn More” link which will take users to a support page containing documentation about data breaches. Further, Breach Alerts would also offer Firefox users an opt-in service to get notified of future data breaches via email.
If you’re a developer interested in the project, you can compile the prototype present in the GitHub and test it in Firefox Developer Edition.
