Download Mozilla Thunderbird 45.7.0

The Mozilla Foundation has released version 45.7.0 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.
