Download Mozilla Thunderbird 45.0

The Mozilla Foundation has released a new version of Thunderbird after a long time that contains more than just some bug fixes. 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 In version 45, among other things, the sender and receiver columns have been replaced by a single correspondent column, the subject line is now also included during the spell check and there are additional options when allowing external content in an email. The complete changelog for version 45.0 looks like this:

New
