New features include:
New Search with Advanced Filtering Tools
- New Search with Advanced Filtering Tools
Search results now include advanced filtering tools. You have the option to filter your results by sender, tag, attachments, people, folder, and mailing list. You can also filter your email using the timeline tool.
- New Global Search Field with Autocomplete
When typing in the Global Search field, Thunderbird autocompletes against your address book. You have the option of searching everywhere or filtering against different parts of the email such as by subject or by sender.
User Experience Improvements
- New Mail Account Setup Wizard
The new Mail Account Setup Wizard matches against a database of email settings from popular mail providers so that you will only need to provide your name, email, and password to set up new mail accounts.
- Redesigned Mail Toolbar
The Mail Toolbar is redesigned to include the new Global Search bar. Buttons such as reply, forward, delete, junk are part of each email message. You can add those buttons back to the main toolbar by customizing the toolbar.
- Tabbed Email
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.
- Smart Folders
The folder pane offers a Smart Folders mode which combines special mailboxes, like Inbox, from multiple accounts. Smart Folders is now on by default.
- New Message Summary
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.
- Message Archive
You can now file messages from your Inbox or other folders into the new Archive folder system.
- Activity Manager
The Activity Manager records all the interactions between Thunderbird and your email provider in one place.
- New Add-ons Manager
The new Add-ons Manager (Tools > Add-ons) can now be used to find, download, and install Thunderbird Add-ons which includes Extensions, Themes, and Plugins. Note that few Add-ons are compatible with this beta at the time of release, as Add-on developers need to upgrade them.
- Improved Address Book
If someone is in your address book, it is indicated by a new star icon which you can click to edit contact details inline. If they are not in your address book, you can add them with one click of the icon. A new birthday field allows you to keep track of your friends' birthdays. You can also add a photo for contacts in your address book.
- Improved Gmail Integration
Better recognition and integration of Gmail's special folders such as Sent and Trash including non-English versions of Gmail. Thunderbird also uses All Mail as the Archives folder.
- For Windows Vista users, Thunderbird 3 is now integrated with Vista search results. On first start, Thunderbird will prompt to install its indexing system into Windows Vista and you can choose to see Thunderbird email and news messages in Windows search results.
- For Mac users, Thunderbird 3 is now integrated with Spotlight, can import from Mail.app, read your OS X address book, and use Growl for new mail alerts.
- IMAP Folder Synchronization
Thunderbird will download IMAP messages by default in the background to allow for faster message loading and better offline operation. This feature can be enabled on an individual folder basis via Folder properties, or for all folders in an account via Account Settings / 'Synchronize & Storage'.

Linux requirements have also changed. Do ensure that compatibility mode for unsupported Windows platforms is disabled for the Thunderbird executable in Windows.
Downloading Thunderbird 3
Mozilla Messaging provides Thunderbird 3 for Windows, Linux, and Mac OS X in a variety of languages. You can get the latest version of Thunderbird 3 here.
For builds for other systems and languages not provided by Mozilla.org, see the Contributed Builds section at the end of this document.
Installing Thunderbird 3
Please note that installing Thunderbird 3 may overwrite your existing installation of Thunderbird on Linux. Windows and Mac OS X will install to different locations, however it is recommended that you check the messages during installation. For all systems, you won't lose any of your messages or address books, but some of your extensions and other add-ons might not work until updates for them are made available.
Users are highly encouraged to install Thunderbird 3 in another folder (on Windows, this is done using Custom Install) and backup their profiles before testing Thunderbird 3.
Uninstalling Thunderbird 3
You can remove Thunderbird 3 through the Control Panel in the Start Menu on Windows, by removing the Thunderbird application on OS X, or by removing the thunderbird folder on Linux.
Removing Thunderbird 3 won't remove your emails or newsgroup messages. This data is stored in your profile folder, which is located in one of the following locations depending on your operating system:
|Windows 2000, XP, Server 2003||Documents and Settings\<UserName>\Application Data\Thunderbird|
|Mac OS X||~/Library/Thunderbird|
|Linux and Unix systems||~/.thunderbird|
Any version of Thunderbird that you install after removing Thunderbird 3 will continue to use the data from this profile folder.
Extensions and Themes
Extensions installed under previous versions of Thunderbird may be incompatible and/or require updates to work with Thunderbird 3. Please report any issues to the maintainer of the extension.
When you install Thunderbird 3 all of your Extensions and Themes will be disabled until Thunderbird 3 determines that either a) they are compatible with Thunderbird 3 or b) there are newer versions available that are compatible.
This list covers some of the known problems with Thunderbird 3. Please read this before reporting any new bugs.
- All Systems
- If you use or had previously used the master password feature, you may be prompted to enter your master password when you first start up Thunderbird. (Bug 338549)
- Your passwords are stored in a new location. If you go back to using a previous version of Thunderbird, or switch back and forth between Thunderbird 3 and an older version, your password lists do not get updated.
- Searching your emails is case sensitive for languages other than English. (Bug 525537)
- If using SSL or TLS, and the certificate that comes from the server is self-signed, expired, or has a domain that does not match the server domain, a dialog will be shown asking if Thunderbird should permanently make an exception for the cert. This should only be done if the error is understood.
- The extended columns in the folder pane were removed in Beta 1. There is an add-on that restores this functionality.
- The compact header view was removed in Beta 3 (Bug 480623); see this blog entry for details.
- Some Thunderbird 2 users upgrading to Thunderbird 3 may not be able to login to their smtp server because the secure authentication setting maybe turned on but not supported by the smtp server. Check your smtp server settings in Tools -> Account Settings -> Outgoing Server, and edit the smtp server with the issue. If use 'secure authentication' is checked, uncheck it and try again. (Bug 522633)
- Thunderbird requires that extensions either come from a secure server using the HTTPS protocol or are digitally signed, or they will fail to install.
- If you are unable to view content for your RSS feeds in the Wide View Layout, you may need to disable the Lightning Calendar add-on if you have it installed or switch to Classic View and restart Thunderbird. (Bug 531397)
- Some emails sent in Plain Text may move the message and some of the buttons out of the message pane. Open the message in a New Tab, resize the window, or change your layout to Classic View or Wide View to view the message. (Bug 530047)
- When working Offline, if you compose an email and select 'Send Later', your message may not be sent if you reconnect automatically to the Internet. You will need need to manually resend the email from your Drafts folder. (Bug 531179)
- In some cases, using 'Save As Template' from the File menu may not work. You can still Save As Template from the email Compose window or drag the message into the Template folder. (Bug 532050)
- Microsoft Windows
- The keyboard shortcut for 'Mark All Read' has changed from Ctrl+Shift+C to Shift+C.
- Poorly designed or incompatible extensions can cause problems with your email client, including make it crash, slow down message display, etc. If you encounter strange problems relating to parts of the email client no longer working, the email client not starting, windows with strange or distorted appearance, degraded performance, etc, you may be suffering from Extension or Theme trouble.
Restart the email client in Safe Mode. On Windows, start using the "Safe Mode" shortcut created in your
Start menu or by running
thunderbird.exe -safe-mode. On Linux, start with
./thunderbird -safe-modeand on Mac OS X, run:
When started in Safe Mode all extensions are disabled and the Default theme is used. Disable the Extension/Theme that is causing trouble and then start normally.
If you encounter strange problems relating to email, feeds or newsgroup messages, it is recommended that you try creating a new profile and attempting to reproduce the problem before filing bugs. Create a new profile by running Thunderbird with the -P command line argument, choose the "Manage Profiles" button and then choose "Create Profile...". Migrate your settings files (Emails, feeds, etc) over one by one, checking each time to see if the problems resurface. If you do find a particular profile data file is causing a problem, file a bug and attach the file, being sure to remove any private information as necessary.
