Nice theme, unfortunately the Persona Switcher add-on isn't available any more, so no light weight theme possible. :(

此意見為舊版本 (3.5.50) 的附加元件。 

Light wight themes are still possible, but right now it takes jumping through a lot of hoops.
Persona Switcher is not abandoned for Thunderbird, a new version will be coming soon.
