I’ve been trying to figure out why, for a few months now, Thunderbird opens with the title bar above the top of the screen and the bottom window border within a few pixels of the bottom of the screen. I have to resize Thunderbird every time I open it.
After a lot of reading today I finally discovered the problem is somehow being caused by Cardbook. If I disable or uninstall Cardbook, the problem goes away. Enable or reinstall it and the problem returns.
Windows 10 Home, 64-bit, 20H2; Thunderbird 78.7.1 32-bit; Cardbook 55.8.
