Using StartupMaster with Thunderbird 3

There is a bug in Thunderbird 3.0 that keeps StartupMaster from working properly.
This will be fixed in Thunderbird 3.0.1, which is planned to ship on January 20, 2010.

Meanwhile, you can download Thunderbird 3.0.1 beta 1.
StartupMaster 1.2 should work fine with this version.

Feel free to mail me if you need more help.
