Firefox 76.0 Changes

Firefox Password Manager (Lockwise) improvements

Mozilla improved the built-in password manager of the Firefox web browser in several ways in Firefox 76.0.

• Breach alerts inform users in the password manager when sites with saved credentials have been breached.
  
• If a breached account password is used on other sites, Firefox will prompt users to update the password on these sites as well to stay secure.
  
• Password generation extended to cover more sites on the Internet. Firefox will suggest a secure complex password when you select the password field.
  
• Firefox protects saved passwords against local snooping if no master password has been set by prompting for the user account password on Windows and Macintosh systems before revealing passwords.
  

Other changes
