Thunderbird 60.3.3

[German]Mozilla’s developers have released the email client Thunderbird version 60.3.3. Here is some information about this maintenance update.


I just started the update search in the Thunderbird after I got this hint, but didn’t get the update yet. According to the release notes, a number of minor bugs have been fixed – here is the translated list of fixes:


  • Thunderbird 60 will migrate security databases (key3.db, cert8.db to key4.db, cert9.db). Thunderbird 60.3.2 and earlier contained a fault that potentially deleted saved passwords and private certificate keys for users using a master password. Version 60.3.3 will prevent the loss of data; affected users who have already upgraded to version 60.3.2 or earlier can restore the deleted key3.db file from backup to complete the migration.


  • Address book search and auto-complete slowness introduced in Thunderbird 60.3.2.
  • CalDav access to some servers not working. Workaround: Set preference network.cookie.same-site.enabled to false.
  • Chat: Twitter not working due to API changes at

The Thunderbird e-mail client is available for Windows 7 and Windows Server 2008 R2 and higher, for macOS 10.9 or higher and for Linux from GTK+ 3.4 or higher. Details can be found here. Further information and downloads can be found on the Thunderbird website.
