Download Mozilla Thunderbird 5.0

The Mozilla Foundation has released the final release of Thunderbird version 5.0. Mozilla Thunderbird is an open source mail and newsgroup client, with features such as support for different mail and news accounts, a junk mail filter, spell checker and a customizable appearance. What once started out as version 3.3 under the codename Miramar, has finally ended up at version 5.0, probably to align the version number with that other Mozilla program. Version 5 includes a new add-on and extension manager, now also shows how large attachments are and is more compatible with the Windows Vista and Windows 7 user interface. The release notes for this version can be found below.

The latest version of Thunderbird has the following changes:

• More responsive and faster to start up and use
• Thunderbird is based on the new Mozilla Gecko 5 engine
• New Add-ons Manager
• Revised account creation wizard to improve email setup
• New Troubleshooting Information page
• Tabs can now be reordered and dragged to different windows
• Attachment sizes now displayed along with attachments
• Plugins can now be loaded in RSS feeds by default
• There are several theme fixes for Windows Vista and Windows 7
• Support for Mac 32/64 bit Universal builds (Thunderbird no longer supports PowerPC on Mac)
• Over 390 platform fixes that improve speed, performance, stability and security
