Thunderbird 102.3.0 released

[German]The developers of Thunderbird have released another update to the email client to version 102.3.0 as of September 20, 2022 (thanks to the reader for pointing this out). It's a bug-fix update, which is supposed to fix a number of issues. Because somehow, the 102 development thread of Thunderbird is a disaster (see Thunderbird 102er: The problem bear).


Thunderbird 102.3.0

According to the Thunderbird release notes, the following changes have been made in this version:

  • Thunderbird no longer attempts to import account passwords when imported from another Thunderbird profile, to prevent profile corruption and permanent data loss
  • The Devtools performance profile now uses Thunderbird presets instead of Web Developer presets

In addition, there are fixes to the following bugs that are listed as fixed:

  • Thunderbird startup performance improvements
  • Saving email sources and images failed
  • An error message was repeatedly displayed when the temporary storage space was full
  • When attaching OpenPGP keys without a specified size to unencrypted messages, a size of zero bytes was displayed for a short time
  • Global search input field initially contained "undefined
  • Mail filter rule "Delete from POP server" was occasionally not triggered
  • Connections to POP3 servers without UIDL support failed
  • POP accounts with the "Fetch headers only" setting downloaded complete messages if the server did not announce the TOP function
  • "File -> New -> Address Book Contact" from the Compose window did not work
  • The "Attach my vCard" option in the compose window was not available
  • Performance when matching a contact with an email address was improved
  • The address book recognized only the first two email addresses of a contact
  • Address Book search and auto-completion failed if a contact's vCard could not be parsed
  • Downloading NNTP messages for offline use failed
  • NNTP client got stuck when connecting to public inbox servers
  • Various visual and UX improvements
  • Various security fixes

This update fixes a number of issues that have been bugging users. I myself am still on the 91 Thunderbird version, as I had problems with empty mails in the 102. So one should be cautious with the update and backup the profile before.

Tip: Going back to an old Thunderbird version after updating to a newer version is rejected if the profile is updated (see also). I fell into this trap some time ago. With an updated profile (without backup) a downgrade is only possible with tricks by starting Thunderbird with the –allow-downgrade option (see also).

The system requirements for the different operating system versions (see here for more details):

  • Windows: Windows 7 or higher
  • Mac: Mac OS X 10.12 or higher
  • Linux: GTK+ 3.14 or higher

The Thunderbird download for free is available here.

    Der Profilordner von Thunderbird ist bei mir für alle Fälle gesichert. Ich bin vor zwei Monaten auf einen neuen Computer umgezogen und habe den zuvor auf dem alten PC gesicherten Profilordner einfach neu eingefügt.

    Hat prima geklappt und Thunderbird sah wieder so aus wie auf dem alten Rechner.

    Meiner Meinung nach ist Thunderbird von allen E-Mailclients noch der beste.
