Download Mozilla Thunderbird 115.3.1

The Mozilla Foundation has released version 115.3.1 of Thunderbird. Thunderbird is an open source client for email and newsgroups, with features such as support for various mail and news accounts. Furthermore, there is a spam filter, spell check, calendar and address book, and it has a customizable appearance. In version 115 we will find, among other things, a new user interface, which has been given the name Supernova by Mozilla. Furthermore, the calendar and address book have been improved, and links are no longer opened in Thunderbird, but in the standard web browser. The changelog for versions 115.3.0 and 115.3.1 can be found below.
