Mozilla Thunderbird is a total redesign of the Mozilla mail component to produce a cross-platform, stand-alone mail application using the XUL user interface language. It has many new features, among them the ability to customize your toolbars the way you want them.

A whopping two years at its second major release, Mozilla's popular desktop email client Thunderbird is now available as the new and improved Thunderbird 3.0, and there's a lot to love in the new Thunderbird.

Thunderbird 3 changes the way you do email with tabbed email, and a new set of search tools helps you find your emails faster.

It turned out that a few weeks were really more like a few minutes. Mozilla Messaging has released the first alpha of Shredder (icon wanted), the code name of Thunderbird 3.
