Thunderbird, Mozilla’s long-running email and calendar app, spent this year reorganizing itself and working on major updates. Now, the development team is starting to show off the next big update, codenamed “Thunderbird Supernova.”
Thunderbird 102 was released in June 2022 as the first phase of the app revamp, with an updated address book, a new Spaces toolbar (similar to the app switcher in Gmail and Outlook), and an account setup process. simplified. Mozilla previously said that a major design update would be coming in 2023, which the development team has codenamed “Supernova.” The actual version number is expected to be 114 or 115, matching whichever version of Firefox is available by then.
The first look at the Supernova update has been posted on the Thunderbird blog: a mockup of the new calendar design in the works. Don’t worry, it still looks like a calendar, but Mozilla has cleaned it up. Weekends can be hidden to save screen space and you can set which days are defined as weekends. The top toolbar will be fully customizable, and while “relaxed” density with plenty of space between buttons will be the default, a narrower interface will also be available.
Mozilla said in a blog post: “We’ve intentionally made this calendar quite busy to demonstrate how the cleaner UI makes the calendar more visually digestible, even when dealing with many events. Dialogs, popups, tooltips, and all calendar companions are also being redesigned. Many of the visual changes will be customizable by the user.”
Thunderbird “Supernova” is still on track to be released next year, while work continues to update the K-9 Mail app for Android into an official Thunderbird client. You can download the current version from the project website.
