Software update: Mozilla Thunderbird 68.2.1

The Mozilla Foundation has released version 68.2.1 of Thunderbird. Mozilla Thunderbird is an open source email and newsgroup client, with features such as support for various mail and news accounts, a spam filter, spell checker and a customizable appearance.

In version 68 we see for the first time a 64bit version for Windows and from this version it is now also possible to migrate a 32bit version to the 64bit version. Furthermore, the program can be managed via policies within corporate environments, filters can now be started periodically and multiple folders can be marked as ‘read’ at the same time. The following improvements have been made in this update:


  • A language for the user interface can now be chosen in the advanced settings (multilingual UI)


  • Problem with Google authentication (OAuth2)
  • Selected or unread messages not shown in the correct color in the thread pane (message list) under some circumstances
  • When using a language pack, names of standard folders weren’t localized
  • Address book default startup directory in preferences panel not persisted
  • Various visual glitches: Conditions in filter editor not high enough, folder location widget not showing folder name, problem with menubar customization, add-on home page links accumulating, theme issues on Windows 7
  • Chat: Extended context menu on Instant messaging status dialog (Show Accounts)

Known Issues

  • LDAP lookup not working when SSL is enabled. Workaround: Disable SSL or switch off option “Query OSCP responder servers” in the certificate settings in advanced options.
