Thunderbird

As of July 2012, Thunderbird has transitioned to a new governance model, with new features being developed by the broader free software and open source community, and security fixes and improvements handled by Mozilla.

Thunderbird is a free, open-source, cross-platform e-mail and news (NNTP) client developed by the Mozilla Foundation. The project strategy is modeled after Mozilla Firefox, a project aimed at creating a Web browser.

Migrated

• 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.

Fixed

• Address book search and auto-complete slowness introduced in Thunderbird 60.3.2
• Plain text markup with * for bold, / for italics, _ for underline and | for code did not work when the enclosed text contained non-ASCII characters
• While composing a message, a link not removed when link location was removed in the link properties panel
