The layout and dialogues have been improved in order to make it easier to understand the information displayed and to find relevant settings. The Account Setup window and the Account Central tab, which appears when you do not have an account setup or when you select an existing account in the folder tree, have both been updated. Much of this will be focused on improved interoperability with the mail part of Thunderbird, as well as improving the user experience of the calendar.

Thunderbird will look at your operating system settings to see if you have enabled dark mode OS-wide and respect those settings. Thunderbird’s new Dark Mode is easier on the eyes for those working in the dark, and it has the added benefit of looking really cool! The Dark Mode even works when writing and reading emails – so you are not suddenly blinded while you work. The compose window now also takes up less space with recipients listed in “pills” instead of an entire line for every address. The compose window has been reworked to help users find features more easily and to make composing a message faster and more straightforward. The new Thunderbird 78 aims to improve the experience of using Thunderbird, adding many quality-of-life features to the application and making it easier to use. Last year’s release focused on ensuring Thunderbird has a stable foundation on which to build.

We encourage those who rely on the popular add-on Enigmail to wait to update until the automatic update rolls out to them to ensure their encrypted email settings are properly imported into Thunderbird’s new built-in OpenPGP encrypted email feature.

Thunderbird 78 is our newest ESR (extended-support release), which comes out yearly and is considered the latest stable release.
