I had the same issue. The problem appears after setting dual monitor, I use fglrx driver. Thunderbird's main window didn't show up when I connected only one monitor. Then I noticed that fglrx driver set the virtual desktop size to the size of the two monitor configuration also when only one monitor is used. After setting the virtual desktop size correctly to the size of one monitor, the thunderbird's main window show up again. I hope this could be helpful.
