Mozilla Thunderbird™, Portable Edition is the popular Mozilla Thunderbird email client bundled with a PortableApps.com launcher as a portable app.


Mozilla Thunderbird is a redesign of the Mozilla mail component. The goal is to produce a cross platform stand alone mail application using the XUL user interface language.
