Downloading and Installing
Before installing, make sure your computer meets the system requirements. Starting with 1.5, Mac OS X users must have Mac OS X 10.2 or greater.
Downloading Thunderbird 126.96.36.199
The Mozilla Foundation provides Thunderbird for Windows, Linux, and Mac OS X.
Linux: GTK2 + XFT (no installer)
Mac OS X: Compressed Disk Image
For builds for other systems and languages not provided by Mozilla.org, see the Contributed Builds section at the end of this document.
Once you have downloaded a Thunderbird installer or compressed archive, follow these instructions to install:
Double click the Thunderbird Setup 188.8.131.52.exe installer to start the install.
Once you have downloaded the Thunderbird 184.108.40.206.dmg file, double click the Thunderbird Disk Image to open it in Finder, and then drag the Thunderbird application onto your hard disk. Drag the icon to your Dock if you want it to appear there.
Extract the compressed archive and run thunderbird
To uninstall Thunderbird, follow these instructions:
From the Start menu, choose Control Panel. When the Control Panel appears, double click Add/Remove Programs. Find "Mozilla Thunderbird (220.127.116.11)" in the list and click Remove to uninstall.
Drag the Thunderbird application to the Trash.
Remove the thunderbird folder.
These instructions leave your profile in place in case you install Thunderbird again in the future. If you wish to remove your profile folder, remove the location described below in the "Profile Folder" section. Note that by doing this you are destroying all of your email, address book data, settings and other information and should you decide to use Thunderbird again you will be starting with a clean profile.
Thunderbird stores your user data in one of the following locations:
|Windows 2000, XP||Documents and Settings\<UserName>\Application Data\Thunderbird|
|Windows NT||WINNT\Profiles\<UserName>\Application Data\Thunderbird|
|Windows 98, ME||Windows\Application Data\Thunderbird|
|Linux and Unix systems||~/.thunderbird|
This list covers some of the known problems with Thunderbird 18.104.22.168. Please read this before reporting any new bugs, and watch it regularly (we'll update it as new bugs are found in the release).
Some users have reported a problem with Thunderbird 22.214.171.124 where e-mail is downloaded from the mail server but not displayed in the Inbox message list. These messages have a particular combination of identical message headers that normal e-mail sending programs will not generate, but some Spam e-mails and e-mails from at least one mailing list will cause this problem.
Thunderbird 126.96.36.199 will have a fix for this issue when it's released in December. Until then, if you suspect you are having this problem, it is recommended that you not compact your Inbox until you've downloaded and run Thunderbird 188.8.131.52 at least once. Thunderbird 184.108.40.206 will recover these missing messages, as long as you don't compact your Inbox. You might also choose to not delete POP3 messages from the server, by checking the "leave on server" check box on the Server Settings page of the Account Settings for the POP3 account.
The situation that causes this problem is a message with identical Message-Id and Reference headers.
We haven't had any reports of IMAP users having this problem, but the symptoms for IMAP users would be that Thunderbird keeps trying to download one or more headers from the server every time Thunderbird is run. Thunderbird 220.127.116.11 will download the header(s) once and resolve the issue.
Extensions and Themes
You may run into issues with our new Extension Compatibility and Update mechanism. There are simple workarounds for each of the three problems we're aware of.
- If after you run the Thunderbird 18.104.22.168 installer, the extension compatibility and update wizard does not appear, go to the Extension Manager and manually check for updates.
- If the Extension Compatibility and Update wizard appears but does not complete, first try to focus some other window and return focus to the wizard. If that does not correct the problem, hit Cancel and go to the Extension Manager and manually check for updates.
- If the Extension Compatibility and Update wizard downloads and installs extension updates but those updates are not applied, open the Extension Manager and manually check for updates.
- On Intel-based Macintosh computers, PowerPC-only binary extensions do not work unless users upgrade to an Intel-native or Universal version or turn on Rosetta. To turn on Rosetta, click on the Thunderbird icon, click "Get Info" and then check the "Run Under Rosetta" box.
Extensions installed under Thunderbird 1.0 may be incompatible and/or require updates to work with Thunderbird 22.214.171.124. Please report any issues to the maintainer of the extension. When you install Thunderbird 126.96.36.199 all of your Extensions and Themes may be disabled until Thunderbird 188.8.131.52 determines that either a) they are compatible with the 184.108.40.206 release or b) there are newer versions available that are compatible. This is because Thunderbird changes from release to release and as such the ways in which some extensions integrate changes, meaning there can be problems when running an older extension with a newer version of Thunderbird. If you find that your favorite Extension or Theme has not been updated to be compatible with this release of Thunderbird, write the author and encourage them to update it.
- Some firewall software may silently block Thunderbird from running. Most firewalls will ask you whether to allow a program to connect to the Internet. It's important that you always grant Thunderbirde access. If you deny access, you must go into the firewall's configuration program and re-allow access. Even when disabled, some firewalls deny access. Here is some more information on configuring your firewall.
- If Thunderbird 220.127.116.11 is installed on a multi-user system in a location which is not writable by users, Thunderbird must be run once by a privileged user. If this is not desirable, an empty file must be created in the following directory: <install-directory>/firstname.lastname@example.org/chrome.manifest.
- The default dictionary is English-only. To add a non-English dictionary, read the installation instructions.
- When switching between using a Global Inbox and using an Inbox for a POP3 account, be sure to make copies of the messages into another folder.
- Software Update will not work if Thunderbird is installed to a location that you do not have write access to, since Software Update needs to replace or create files in this location.
- When installing as a restricted access user on a shared machine into a location that you can write to, there may still be negative side effects (default email/other keys not being set correctly). The email client should still function however. When installing as a restricted access user do not attempt to install over an installation in a restricted-access/shared location as this may destroy that installation.
- Windows users can sync their address book with a Palm device by installing the Palm Sync extension for Thunderbird. Save the file locally and install it from the extensions dialog in Thunderbird. The extension will not show up in the list of extensions. You will have to restart Thunderbird after installing the extension before it will take effect.
- If you are running Thunderbird 1.5 or Thunderbird 18.104.22.168 on Macintosh computers with Intel Core processors under Rosetta, you will get upgraded to a PowerPC-only, Thunderbird 22.214.171.124 product via the automated update system. You will need to download the Thunderbird 126.96.36.199 Universal Binary build from www.mozilla.com to take advantage of the native support for Intel-based Macintosh computers.
- There is no Talkback on Intel-based Macs when running natively or under Rosetta. The Apple Crash report program should launch in the event of application crashes.
Linux and Unix systems
GNOME integration does not work properly with Fedora Core 3.
Users of Fedora Core 3 will need to download and install
After installing the RPM, perform the following command in the directory you
installed Thunderbird into (you will need write permission):
The next time you start Thunderbird, GNOME integration should be functional.
What can I do to help?
We need all the exposure we can get. Make it your mission to convert as many of your friends, family members and coworkers as possible. If you're a student, get it distributed at your college. Submit a story to Slashdot and other news sites about the release. Make some noise on your blog. Mass distribution via the Internet is possible -- look at Kazaa.
Why haven't you responded to the mail I sent you?
Use the forums. The Thunderbird team reads them regularly. We all get a lot of email and your email may get lost.
- Where can I get themes and add-ons (extensions)?
