We asked Jon Hicks, the creator of the original Firefox and Thunderbird logos, to re-imagine his iconic design in light of Thunderbird’s exciting future. 

We’re back with another progress report as we continue improving K-9 Mail for its transformation to Thunderbird for Android! We spent most of the previous month preparing for a new stable release. In April 2023, we finally published K-9 Mail 6.600.

Last month we reported on the progress we made in turning K-9 Mail into Thunderbird for Android. Since then a month has passed, so it’s time for another detailed update. Let’s dive in!

While K-9 Mail / Thunderbird for Android is developed in the open, following its development on GitHub can be somewhat tedious for a casual observer. So we’re trying something new and summarizing the most notable things that happened in the past month.

Last week we showed you the new Swipe actions in K-9 Mail 6.400. Today, it’s something even more exciting: a completely redesigned message view! 

The path to bringing you a great email experience on Android devices begins with K-9 Mail, which joined the Thunderbird product family earlier this year. As we work towards a modern redesign of desktop Thunderbird, we’re also working towards improving K-9 Mail as it begins its transition to Thunderbird mobile!

Today, we announced our detailed plans for Thunderbird on mobile. We also welcomed the open-source Android email client K-9 Mail to the Thunderbird family. Below, you’ll find an evolving list of frequently asked questions about this collaboration and our future plans.
