This is a great add-on and (I think) a tray option should be mandatory for EVERY email client. If not for this extension I would simply not use Thunderbird (yes it IS that important).
There is one bug, the "close button minimizes to tray" option doesn't work (It works fine under Firefox however). This extension would be perfect if that were fixed in the next version. I am using Thunderbird on Ubuntu, I don't know if the problem exists on other Linux distros.
