Download Mozilla Thunderbird 52.2.0

The Mozilla Foundation has released version 52.2.0 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.
