More about the integrated features

Firefox Lockwise comes with a feature that warns of logins leaked in data breaches.

The release of Firefox 76 looks promising as the integrated Lockwise password manager is programmed to issue warnings at the event of a website data breach that has saved account credentials.

How would you come to know about the data leak?

The data leak alerts will be shown in the Lockwise password manager and will appear in red as a “Website Breach” alert.

What’s more?

Lockwise password manager will give users a heads up in case an account is found in a data breach along with the same password being used on other websites.

The OS password prerequisite

Having a master password setup in Firefox Lockwise is essential as the password manager will need you to type in the Windows or MacOS password before it can permit you to view saved login credentials.

The added security step is designed to protect your saved login credentials from being viewed by people who may have access to your machine.

Additional details

The picture-in-picture Firefox 76 allows you to detach a video that you are watching and can float it on top of the screen, to help you continue watching it while you are toggling between applications.
