Mozilla's released a few weeks ago version 3 beta 3 of it Email Client, Thunderbird. This beta release still full of bugs and should not be used on a production box or as used as your principal email client. See the list of bugs in Thunderbird 3 beta 3 before going ahead to install.

Mozilla Thunderbird 2.0.0.4 was released on Thursday 14th June. This update to the Mozilla Corporation's mail client includes bug fixes but no new features. For the first time, this release of Thunderbird is available in Korean.

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.

Mozilla Thunderbird 2.0.0.5 has been released and is currently being distributed to Thunderbird 2 users via the application's built-in software update system.

Cyber Cynic: "But, then Mozilla put Thunderbird on the back burner to focus its attention on Firefox, and, frankly, Thunderbird slowly aged into a second-rate e-mail client. Now, at long last, a new, and vastly improved version of Thunderbird has just been released, and, let me tell you, it's back to being great."

Among desktop Mail clients, Mozilla Thunderbird is still a popular choice. Thunderbird unites many advantages, including the flexibility we all know from Firefox. One of the greatest joys for me is customizing Thunderbird’s look and feel.
