Firefox 78 and esr version

There are two variants: the 'normal' Firefox 78 and the esr edition. The abbreviation esr stands for Extended Support Release, a variant that provides a longer support of about 1 year for the version in question, while the normal variant is updated to new versions after some time.

The release notes of Firefox 87 point out several new features. The Protections Dashboard contains consolidated reports on protection activity, data breaches and password management.

  • Track directly from the dashboard how many security breaches you have resolved.
  • See if one of your stored passwords could have been exposed by a data breach

To view the dashboard, type about:protections in the address bar or select "Protections Dashboard" from the main menu.
