Hello Carsten! My bad, too many years using other distributions embedded with a "store" to install software...
What I actually meant by "store" was the Software app (Gnome software) that is delivered by default within Debian. I installed Thunderbird from there: [image: imagen.png] This is important, if I don't change the language after installing it, Thunderbird works just fine but if I add more languages and select e.g. English UK or Spanish Spain, the UI breaks, the only way I found out to fix it back was to delete the folder ".thunderbird" that gets created in my home folder every time I open Thunderbird. After battling a little bit, I gave up upon using Software app in order to install TB and finally install Snap store to install their Snap, I don't like that way but I needed to get back to work asap. Thunderbird is stable in Debian when installed from the Snap store. I wish I can get you a screen capture but that would mean I have to uninstall TB then reinstall it using GSoftware, change languages and restart TB, that would be inconvenient tonight but I will gladly do it during the weekend. Have a great day!
