The existing 'balloon' notifications also stick around forever in the Windows 10 notification bar (Win+A). It might not be possible to display notifications when Thunderbird is not running, but I agree that the existing notifications should integrate a bit better with the OS. Jul 10, 2017 Windows 10 includes enhanced app notifications that can display on the start menu, in the Action Center, and even on a flyout above the Notification bar. The Mail app uses the Windows notification system to notify you of new emails. The interesting thing is that I am getting notifications on the Thunderbird mail application. I have checked the notifications settings and they are switched to the on position. I am able to watch videos with full volume. I am running Windows 10 with all updates installed. Thanks in advance for your help. Nov 25, 2020 Mailbox Alert 0.26 by Tjebbe. Mailbox Alert allows you to specify, for each seperate mail folder, a message, sound and/or a system command that will be executed when new mail is found there. Mozilla’s Thunderbird email client is expected to get support for notifications natively in Windows 10, meaning that they will be logged into the Action Center for later viewing should they appear.

System Requirements

Before installing, make sure your computer meets the system requirements.

Downloading

Mozilla provides Thunderbird for Windows, Linux, and Mac OS X in a variety of languages. You can get the latest version of Thunderbird 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

Please note that installing a new version of Thunderbird will overwrite your existing installation of Thunderbird. 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 they are updated by the author.

Uninstalling

You can remove Thunderbird 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.

Thunderbird Sound Notification

Removing Thunderbird 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:

Any version of Thunderbird that you install after removing Thunderbird 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. Please report any issues to the maintainer of the extension.

When you install Thunderbird all of your Extensions and Themes will be disabled until Thunderbird determines that either a) they are compatible with this release or b) there are newer versions available that are compatible.

Known Issues

This list covers some of the known problems with Thunderbird. Please read this before reporting any new bugs.

• Thunderbird 10 may stop working with some mail and LDAP servers that are incompatible with the way Thunderbird prevents CBC-related attacks on TLS 1.0 and SSL 3.0. Contact the server vendor for a fix. We have heard of issues with these servers:
  • Kerio Connect - we are working with the vendor to resolve the issue. See Bug 723551 for more information
  • Merak Icewarp - we are working with the vendor to resolve the issue. A possible work around has been provided, see Bug 723109 for more information
• Some users may experience a crash when importng from Microsoft Outlook (Bug 723105)
• 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)

Troubleshooting

• 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 - select Help followed by Restart with Add-ons disabled. 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.
