I've made a simple app for OSX which displays the Thunderbird icon in the menu bar and the number of unread e-mails next to it. It uses this extension and works quite well. There is also a version with white text for dark menu bars. The only thing is that the extension takes some time (1-2 secs) before it detects the number has changed and writes it into the file.

Check it out here:

This review is for a previous version of the add-on (0.1).
