At long last, Mozilla Thunderbird 3.0 has been officially released. Thunderbird 2.0
was released about two and a half years ago (April 2007) and while Mozilla Firefox has sped along with a number of releases in the 3.x series, Thunderbird has not. However, the 3.0 release of this Mozilla mail client should be rather great and does boast many improvements.
Mozilla Thunderbird 3.0 delivers tabbed support (similar to the Firefox implementation), a new search interface, a message archive, smart folders, improvements to the user-interface, a mail account setup wizard, an activity manager, and much more.
