Windows/Mac/Linux:Mozilla刚刚以thunderbird3beta3的形式发布了一个新的beta版桌面电子邮件应用程序，增加了更好的Gmail集成、智能文件夹等等。

这一更新承诺，除了我们在Mozilla发布thunderbird3beta2时看到的改进之外，还将为开发者和用户提供一些改进。明确地：

• Tabbed Email Messages
• Double-clicking or hitting enter on a mail message will now open that message in a New Tab window. Middle-clicking on messages or folders will open them in a Tab in the background. When quitting Thunderbird, visible tabs will be saved and will be restored when you open Thunderbird the next time. There is also a new Tab menu on the Tab toolbar to help you switch between Tabs.
• New Message Summary View
• Selecting multiple messages will give you a summary view of the emails you have selected.
• Column Headings
• The column headings that are displayed and the order in which they are displayed can now be set on a per-folder basis.
• Smart Folders
• The folder pane offers a Smart Folders mode which combines special mailboxes (e.g. Inbox) from multiple accounts together.
• Improved Gmail Integration
• Better recognition and integration of Gmail's special folders such as Sent and Trash including non-English versi*** of Gmail. Thunderbird also uses All Mail as the Archives folder.
