Download Mozilla Thunderbird 45.4.0

The Mozilla Foundation has released version 45.4.0 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 and this time again the changelog only shows bug fixes.

Fixed

• “Apply columns to…” did not honor special folders
• Threading broken when editing message draft, due to loss of Message-ID
• Mail saved as template copied In-Reply-To and References from original email.
• Additional spaces were inserted when drafts were edited.
• Recipient addresses were shown in red despite being inserted from the address book in some circumstances.
• Display name was truncated if no separating space before email address.
