Mozilla this week upgraded Firefox to version 85, adding to its overarching emphasis on privacy by isolating supercookies that some sites rely on to track users’ movements on the web.
Engineers also patched 13 vulnerabilities, five of which were marked “High,” Firefox’s second-most-serious label.
Firefox 85 can be downloaded for Windows, macOS, and Linux from Mozilla’s site. Because Firefox updates in the background, most users can simply relaunch the browser to get the latest version.
