Later this year, Mozilla will update the Firefox desktop theme with the new Proton interface. The visual overhaul is expected to include:

  • An optimized hamburger menu: Mozilla removes the icons and makes the menu completely text-based. Some options are also renamed, combined, or completely removed.
  • A personalized new tab: You can change the look and layout of the new tab, including the number of links displayed, recommendations, and new snippets.
  • Info bar and notification changes: Firefox notifications have more color to make the messages more personal.

These are the most important changes that we know due to early looks and leaks;; The final version of Firefox 89’s Proton theme may have other tweaks and updates as well. The redesign will start in May. However, you can get a first overview by installing the Firefox Beta, Nightly or Dev build and enabling the new changes to the user interface in the experimental settings of the browser.

Enable the Proton interface early in Firefox Beta, Nightly or Dev versions

All available Proton UI elements will be displayed after restarting Firefox. Some users may not see that every new user interface changes immediately. So be sure to check in the coming weeks to see if Mozilla has anything new to offer you.
