The team behind the Thunderbird email client has released Thunderbird 68.9.0 Stable to the public. Thunderbird follows the release schedule and versioning of Firefox ESR, Extended Support Release. Mozilla decreased the time between Firefox releases recently and that is the core reason why you see more Thunderbird releases coming out.

Thunderbird 68.9.0 is already available. The email client's integrated update check should pick up the new version and offer it for download to users. Thunderbird users who don't want to wait this long can select Help > About Thunderbird to run a manual check for updates or download the new release from the official project website to install it manually.

Thunderbird 68.9.0

The Thunderbird 68.9.0 release notes lists three bug fixes and security fixes.

The bug fixes corrected the following issues in previous versions of the email client:

  1. An issue that prevented users from removing custom headers used for searching of filtering emails.
  2. The today pane of the built-in Calemdar was updated before all data was loaded.
  3. Unspecified stability improvements.

Information about the security updates in Thunderbird 68.9.0 has not been released yet. The Security Fixes page lists Thunderbird 68.8.0 as the last version at the time of writing. The release is delayed usually to push updates out to systems before information about potential security issues is revealed to the public.

The next major version of the Thunderbird email client will be released on June 30, 2020. Thunderbird 78.0 is a major release; it will make changes to the add-on system and will lead to add-on incompatibilities.  Classic extensions won't be supported anymore and developers have to update the extensions so that the extensions remain compatible with Thunderbird.

One developer decided to create a campaign on Kickstarter to gain enough funding to update Thunderbird extensions for Thunderbird 78.0 compatibility. The campaign was successful as the developer managed to collect more than $51,000 U.S. Dollars.

Now You: Do you use Thunderbird?

    Update problem solved:

    A word about instructions:
    The site is explaining a NEW install. For an update use:

    To install this PPA:
    sudo add-apt-repository ppa:mozillateam/ppa
    sudo apt-get update
    sudo apt-get install

    Note that ppa is for stable releases. If you want other choices, use what is shown in the original instructions and you will be told that the “thunderbird-stable” does not exist. But it will tell you what options you can choose to replace “thunderbird-stable”.

    Happy hunting!

    I did the install, will test it next. Report back later.
    where is one of the packages below.

    Ubuntu 16.04 does not have Thunderbird 68.9.0
    I have a dual boot with 16.04 and Win10. I have a shared profile area.
    Win10 did a silent update of Thunderbird to 68.9.0 and it installed corruptly, destroying major parts of the profile and mail folders. I recovered some.
    I went to Thunderbird and downloaded 68.9.0 and installed it under user. When turned on, with the -P option identifying the profile location, it said I had an older version and Thunderbird versions must match. “Would you like to create a new profile?” I said no, and restarted with ID of my profile. When open it was 68.8.0 even though the file I installed said 68.9.0.

    Something Dodgy there

    After a lot of work I salvaged a lot of files (lost mre than saved) under Win10. Cannot open Linux until I can be sure I have a 68.9.0 install.

    anyone know whai I did wrong?

    I have Outlook as part of Office 2019. Outlook is good, but, as a home rather than office user, I think Thunderbird is so much simpler to use and the layout is better. Having said that I’ve stuck with version 52.9 because there seem to be very few complete themes for the latest Thunderbird. I have the Silvermel and Charamel XT add on which, unfortunately, hasn’t been updated for Thunderbird 68 on. Until it, or something equally easy on the eye, is available, l’ll stick with v52.9.
    If more complete themes are now available I’d be interested to know.

      “DeepDark for Thunderbird” by steva is a complete and fully compatible TB addon.

    Hi Martin,

    Do you have any idea on how to change the Dark mode back to light in Thunderbird?
    The messages are unreadable in Dark mode.
    I am ccurently using TB 77b3.

    Searching the Web doesn’t seem to provide me with a solution.

      Hi Steve,
      you need to open the Add-ons Manager via Tools > Add-Ons. Select Themes, and active the Light theme there.

    Yes, Loving it.

    There are some still not working for me things like the thunderbird is an icon (going smaller) appearance in the notification area. I have tried several (apps) things but probably I am doing something wrong.

    Maybe Mozilla Thunderbird is willing to build this function standard in the program?
