Thunderbird is a full-featured email, RSS and newsgroup client that makes emailing safer, faster and easier than ever before. More information about Thunderbird is available.
These Release Notes cover what's new, download and installation instructions, known issues and end user support / feedback for the Thunderbird 1.0.2 release. Please read these notes and the bug filing instructions before reporting any bugs to Bugzilla.
Thunderbird 1.0.2 is a security and stability update that is part of our ongoing program to provide a safe Internet experience for our customers. We recommend that all users upgrade to this latest version.
To avoid crashes or other problems, do not install a new version using the installer into the same folder as an older zipped installation.
Here's what's new in Thunderbird 1.0.2:
- Several security fixes.
- Improved stability
Downloading and Installing
Before installing, make sure your computer meets the system requirements.
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:Note: Mozilla Thunderbird will create its own user profile information if it does not exist. If you have previously installed the Mozilla Suite, Thunderbird will not interfere with your Mozilla Suite profiles.
Double click the Thunderbird Setup 1.0.2.exe installer to start the install.
Double click the Thunderbird 1.0.2.dmg.dz Disk Image to uncompress and mount it. Your browser may have already done this for you. Double click the Thunderbird Disk Image to open it in Finder and drag the Thunderbird application onto your hard disk. Do not double click the icon in the disk image! Be sure to drag the Thunderbird application out of the disk image and onto your Hard Disk before running it. 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 (1.0.2)" 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\Mozilla Thunderbird|
|Windows NT||WINNT\Profiles\<UserName>\Application Data\Mozilla Thunderbird|
|Windows 98, ME||Windows\Application Data\Mozilla Thunderbird|
|Linux and Unix systems||~/.thunderbird|
Extensions and Themes
When you upgrade to a new version of Thunderbird all of your Extensions and Themes will be disabled until Thunderbird determines that either a) they are compatible with the new 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 authors and encourage them to update it.
This list covers some of the known problems with Thunderbird 1.0.2. Please read this before reporting any new bugs, and watch it regularly (we'll update it as new bugs are found in the release).
- If you install Thunderbird on a multi-user system in an area in which there is restricted access privileges, you must run Thunderbird as a user with access to that location upon installation so that all initial startup files are generated. If this is not done, when a user without write access to the install location attempts to start Thunderbird, they will not have sufficient privileges to allow Thunderbird to generate the initial startup files it needs to operate.
- When upgrading, all your Extensions and Themes will be disabled. This is not an issue, but it may appear to be one (hence its listing here). For rationale, see "Extension and Themes" above.
- 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.
- By default, to protect your privacy, Thunderbird blocks cookies for all messages. This behavior can be problematic for some RSS feeds that require cookies. You can enable cookies by adding the line: user_pref("network.cookie.cookieBehavior", 3); to your profile's prefs.js file.
- Return Receipts (MDN) are not working properly for POP3 accounts.
- 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.
- Do NOT run Thunderbird from the Disk Image! - doing this will cause an infinite restart loop (the symptom of which is a Thunderbird icon that bounces briefly in the Dock then disappears and reappears, bounces and disappears, over and over). To break Thunderbird out of this loop, open a Terminal and type "killall thunderbird-bin" and press enter. Install Thunderbird to a location you have write access to and try again. When installing on a multi- user limited access system, install it into a shared location as administrator, run it once and then all users should be able to access it.
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)?
Who is working on Thunderbird?
Lots of people. See Help->About Mozilla Thunderbird, Credits for a list of some of the people who have contributed to Thunderbird.
