Download Mozilla Thunderbird 52.3.0

The Mozilla Foundation has released version 52.3.0 of Thunderbird. Mozilla Thunderbird is an open source email and newsgroup client, with features such as support for several mail and news accounts, a spam filter, spell checker, and a customizable look and feel. In Thunderbird, new functionality is rarely added. New in version 52 is, among other things, that images are now added as data URIs in messages. In addition, there is now a drop-down menu that allows you to quickly customize the way folders are displayed. In addition, in Lightning it is now possible to edit events in tabs. The following issues have also been fixed in this update.

Fixed

• Unwanted inline images shown in rogue SPAM messages
• Deleting message from the POP3 server not working when maildir storage was used
• Message disposition flag (replied / forwarded) lost when reply or forwarded message was stored as draft and draft was sent later
• Inline images not scaled to fit when printing
• Selected text from another message sometimes included in a reply
• No authorization prompt displayed when inserting image into email body although image URL requires authentication
• Large attachments taking a long time to open under some circumstances

Known Issues

• On Windows, “Send to > Mail recipient” does not work. Workaround: Install the Microsoft Visual Studio 2015 redistributable runtime library or the Universal C Runtime for Windows Server.
• Multiple requests for master password when GMail OAuth2 is enabled
