Thunderbird 115 Supernova FAQ

This document answers questions for new users of Thunderbird 115 (Supernova), in particular users who have upgraded from a previous version. __TOC__ == Where can I find more information on changes and new features in Thunderbird 115 Supernova? == Please refer to the following documents: * [[New in Thunderbird 115 Supernova]] * [https://www.thunderbird.net/en-US/thunderbird/115.0/releasenotes] * [https://www.thunderbird.net/en-US/thunderbird/releases/] (all releases, including details on the latest minor releases) == Why doesn’t Thunderbird follow the operating system accent colors? == Thunderbird colors are fully customizable using a custom theme. Custom themes can follow the OS colors or use whatever colors the theme writer wants. Out of the box, we provide a default set of colors that follow our brand identity in order to always guarantee AAA accessibility and readability between foreground and background elements.. Customizing it the way users want is always supported and welcomed, to the point that the new UI is even more easily customizable with a few CSS variables. We just do not have the resources and time to support every single OS variation, especially Linux Desktop Environment variations, and it is more sustainable to defer this kind of support to custom themes. We encourage and welcome any cool custom themes especially for Linux since most of the team uses Linux (and would consider shipping them with the Flatpak).
