What's New in Thunderbird 3.1.13
Thunderbird 3.1.13 fixes the following issues in Thunderbird 3.1.12:
- Revoked the root certificate for DigiNotar due to fraudulent SSL certificate issuance (see bug 682927 and the security advisory)
Before installing, make sure your computer meets the system requirements.
Please note that Thunderbird 3.1 no longer supports versions of Windows prior to Windows 2000 (e.g. Windows 95, 98, ME, and NT) and Mac OS X versions prior to 10.4 Tiger. Linux requirements have also changed. Do ensure that compatibility mode for unsupported Windows platforms is disabled for the Thunderbird executable in Windows.
Downloading Thunderbird 3.1
Mozilla provides Thunderbird 3.1 for Windows, Linux, and Mac OS X in a variety of languages. You can get the latest version of Thunderbird 3.1 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 3.1
Please note that installing Thunderbird 3.1 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 3.1 in another folder (on Windows, this is done using Custom Install) and backup their profiles before testing Thunderbird 3.1.
Uninstalling Thunderbird 3.1
You can remove Thunderbird 3.1 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 3.1 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 3.1 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 3.1. Please report any issues to the maintainer of the extension.
When you install Thunderbird 3.1 all of your Extensions and Themes will be disabled until Thunderbird 3.1 determines that either a) they are compatible with Thunderbird 3.1 or b) there are newer versions available that are compatible.
This list covers some of the known problems with Thunderbird 3.1. Please read this before reporting any new bugs.
- All Systems
- Your passwords are stored in a new location. If you go back to using Thunderbird 2, or switch back and forth between Thunderbird 3.1 and Thunderbird 2, your password lists do not get updated.
- Extended columns in the folder pane were removed in Thunderbird 3. There is an add-on that restores this functionality. You can also install this add-on using the Migration Assistant.
- The compact header view was removed in Thunderbird 3 (Bug 480623); see this blog entry for details. There is an add-on that offers similar functionality. You can install this add-on using the Migration Assistant.
- Thunderbird 3.1 requires that extensions either come from a secure server using the HTTPS protocol or are digitally signed, or they will fail to install.
- 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.
- 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)
- 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)
- Smart Folders has been renamed to Unified Folders and can now be edited.
- Plugins will no longer show in add-on manager as they have now been globally disabled due to performance issues. Mozilla does not recommend enabling plugins due to possible security issues.
- Microsoft Windows
- The keyboard shortcut for 'Mark All Read' has changed from Ctrl+Shift+C to Shift+C.
- If you are using the Kaspersky Anti-Spam Extension from Kaspersky Internet Suite 2010, it is disabled in Thunderbird 3.1 (Bug 533692)
- If you are using the Kaspersky Anti-Spam Extension from Kaspersky Internet Suite 2011, issues within the Kaspersky Software may cause it to be broken with this update. Kaspersky currently expect to release an update to their software in November or December 2010 to fix this issue.
- 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.
