Download and Install Mozilla Thunderbird 3 Ubuntu 9.10 “Karmic Koala”

Mozilla Thunderbird is a free, open source, cross-platform e-mail and news client developed by the Mozilla Foundation.

The new features in Thunderbird 3 help users work faster while providing the advanced flexibility and security they are accustomed to with all versions of Thunderbird.

Key new features in this release include:

* Tabbed Email: Provides the ability view individual emails and folders in tabs, and web pages via add-ons in tabs so users can quickly jump between them, just as one manages web pages in Mozilla's Firefox. Folder tabs are remembered, so Thunderbird starts up pre-configured and personalized to each user.
* Filtered Search: Designed with search in mind, the new search interface in Thunderbird 3 contains filtering and timeline tools to help users quickly and accurately pin-point the exact email by word matches, correspondents or even attachment types at the moment they need it, all based on analysis of the user's own emails.
