FossaMail 27.0.0 (x86/x64) | 69 MB

FossaMail is a mail, news and chat client for Microsoft Windows based on Mozilla Thunderbird. It is a re-build of Mozilla Thunderbird ESR (Extended Support Releases) that has been optimized and reconfigured by the same developer behind Pale Moon browser. Is built from source with the main goal of providing a fast and reliable Mozilla Thunderbird-based client that should work with all existing add-ons and plugins that were developed for Mozilla Thunderbird.

It uses its own profile folder (default location to "%APPDATA%\FossaMail") and therefore has no interaction with any current installation of Mozilla Thunderbird. Please note that Windows XP is not supported and you need at least Windows Vista (or a newer edition of Windows), a CPU (processor) with SSE2 support (most modern CPUs support this, check this section - "CPUs supporting SSE2") and obviously, enough space on your computer hard drive to store your e-mails along with an Internet connection.

Features:
Is built from source with compiler optimizations geared towards an as stable and smooth operation of the client as possible (Pale Moon-alike optimizations).
Uses the Pale Moon browser core as its back-end. The client is therefore based on Pale Moon rather than other Mozilla-derived mail clients.
Uses its own profile folder on your system. This means it will not interfere with existing Thunderbird installations.
The default profile location is %APPDATA%\FossaMail
Should be compatible with all Thunderbird (v24/25b era) add-ons and plugins.
Is available in 32-bit (x86) and 64-bit (x64) versions for both Windows and Linux.
Comes with an optional calendar/organizer add-on (Lightning, available from the download location below) that will allow it to be used in a Microsoft Outlook style information manager fashion.

Whats New:
This is a major new milestone update!
Both the application code and the back-end code have received a complete overhaul.

A brief summary of the biggest changes:

Switched the rendering engine to Goanna.
Switched the back-end code to Pale Moon 27.
Hoisted most of the application code to be Thunderbird 38 equivalent in functionality.
Added support for a few additional authentication methods for connecting to mail servers.
Integrated lightning into the application (no longer a separate download).
