Mozilla Thunderbird is a free, open source, cross-platform email, news and chat client developed by the Mozilla Foundation. The project strategy is modeled after Mozilla Firefox, a project aimed at creating a web browser. Thunderbird is an email, newsgroup, news feed and chat (XMPP, IRC, Twitter) client. Thunderbird provides enterprise and government-grade security features such as SSL/TLS connections to IMAP and SMTP servers. Extensions allow the addition of features through the installation of XPInstall modules via the add-ons website which also features an update functionality to update the extensions. Here's what's new in Thunderbird 1.5: Automated update to streamline product upgrades. Notification of an update is more prominent, and updates to Thunderbird may now be half a megabyte or smaller. Updating extensions has also improved. Sort address autocomplete results by how often you send e-mail to each recipient. Spell check as you type. Improvements to product usability including redesigned options interface, and SMTP server management.
