Thunderbird is a full-featured e-mail, RSS and newsgroup client that makes e-mailing safer, faster and easier than ever before. More information about Thunderbird is available.
Given the maturity of the underlying Mozilla code, Thunderbird is very usable as your primary e-mail client. However, it is considered a Technology Preview, and as such is assumed to have defects. See the License Agreement for more information.
These release notes cover what's new, download and installation instructions, known issues and end user support / feedback for the Thunderbird 0.9 release.
Please read these notes and the bug filing instructions before reporting any bugs to Bugzilla. We want to hear your feedback about Thunderbird. Please join us in the Mozilla Thunderbird Support forum, kindly hosted by MozillaZine.
Saved Search Folders display messages based on previously set search criteria. For example, instead of filtering messages into a new folder, you could create a Saved Search Folder that lists all the messages received from a certain person over the past 30 days, even if those messages are stored in different folders and subfolders.
You can now group messages in a folder by attributes such as date, sender, priority or a custom label. For instance, a folder grouped by date will group messages from today, yesterday, last week, etc. into self-contained groups in the message list pane. (View > Sort By > Grouped By Sort)
Messages with attachments now get marked as such in the message list pane immediately and not when the message is displayed.
Improvements to Thunderbird's Global Inbox support for POP3 users.
The new quick search bar introduced in 0.8 now features a clear button when search text is present inside the quick search box.
Fixed a regression introduced in 0.8 where a user could not change the local folder path in the Account Manager.
Improved offline support including fixes for common offline-related problems.
Improved privacy controls block remote content in e-mail messages from senders not in your address book.
Long file attachment names are no longer truncated in the message pane.
Bug fixes too numerous to mention!
