There are a few tabs in a single window
and there is a "Downloads" window opened... 
If I close the main window and then start firefox using a shortcut, a window with the startpage will be opened...

I had lost plenty of tabs by the day I installed "Tab Mix Plus" :)

Reproducible: Always

Steps to Reproduce:
1. Open a few tabs in a single window
2. Open a "Downloads" window
3. Close the main window
4. Start firefox main window using shortcut
Actual Results:  
Main window is opened with the start page.

Expected Results:  
Tabs are restored (cause there were no other windows with pages!)
