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.
