Thunderbird is a free, open-source, cross-platform application for managing email and news feeds. It is a local (rather than a web-based) email application that is powerful yet easy-to-use. Thunderbird is developed, tested, translated and supported by the folks at Mozilla Corporation and by a group of dedicated volunteers. Thunderbird gives you control and ownership over your email. There are lots of add-ons available for Thunderbird that enable you to extend and customize your email experience.
Thunderbird gives you IMAP/POP support, a built-in RSS reader, support for HTML mail, powerful quick search, saved search folders, advanced message filtering, message grouping, labels, return receipts, smart address book LDAP address completion, import tools, and the ability to manage multiple e-mail and newsgroup accounts.
What's new in Thunderbird 68.3.1:
In dark theme unread messages no longer shown in blue to distinguish from tagged messages
Account setup is now using client side DNS MX lookup instead of relying on a server.
Searching LDAP address book crashed in some circumstances
Message navigation with backward and forward buttons did not work in some circumstances
WebExtension toolbar icons were displayed too small
Calendar: Tasks due today were not listed in bold
Calendar: Last day of long-running events was not shown
- 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 compatible add-on via the Add-ons Manager or via addons.thunderbird.net.
