Download Mozilla Thunderbird 68.3.0

The Mozilla Foundation has released version 68.3 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 checking 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:

New:

• Message display toolbar action WebExtension API
• Navigation buttons are now available in content tabs, for example those opened via an add-on search

Changed:

• “New email” icon in Windows systray changed from in-tray with arrow to envelope

Fixed:

• Icons of attachments in the attachment pane of the Write window not always correct
• Toolbar buttons or add-ons in the menubar not shown after startup
• LDAP lookup not working when SSL was enabled. LDAP search not working when “All Address Books” was selected.
• Scam link confirmation panel not working
• In Write window, the Link Properties dialog wasn’t showing named anchors in context menu
• Calendar: Start-up failed if the application menu is not on the calendar toolbars
• Chat: Account reordering via drag-and-drop not working on Instant messaging status dialog (Show Accounts)

Known Issues

• When upgrading from Thunderbird version 60 to version 68, add-ons are not automatically updated during the upgrade process. They will however be updated during the add-on update check. It is of course possible to reinstall combatible add-on via the Add-ons Manager or via addons.thunderbird.net.
