Why does Thunderbird open two separate windows, if I close one, both shut down.
As in description. When I start Thunderbird it starts two separate windows. If I close one, the other one also closes. It’s possible to work in both windows, but they don’t sync until restarted.

Are you using the MinimizeToTray add-on, or a similar one?
If so, disable it, restart Thunderbird like you normally do, and re-enble it if all goes well. You should also temporarily start Thunderbird in Safe Mode to see if any other add-on is causing the issue. In that mode, Thunderbird should work as expected. Note that the original MinmizeToTray add-on is rather outdated, so if you can pinpoint the issue to that add-on, you could try finding a replacement.
In general, this should solve it too:
- Go to File > Close (NOT Quit, but Close), that closes the window.
- With the last window, quit.
- Open Thunderbird. There should be only one window, as expected.
