Thunderbird opens twice always
Follow these steps:
- Disable "MinimizeToTray Plus" in menu "Tools/Add-Ons"
- Exit Thunderbird (be sure that the process is not running)
- Open Thunderbird (in my case, I had the same two windows problem the first time)
- Now Thunderbird runs without the MinimizeToTray Plus add-on
- Close one of the window
- Re-enable your "MinimizeToTray Plus" add-on
- Exit and restart

I had the same on one of the machine I manage and the solution was pretty simple in the end. On one of the two windows just do file->Close. It closes just that window and not the other. Then close TB and reopen it.
I've seen quite a lot of mention of problems with add-ons, but in this case there were none and none of the other solutions worked.

In preferences of FireTray (my version is 0.4.8) please check the field:
[] Only last window can be hidden
