FossaMail (32-bit) v38.2.0

FossaMail is a free, open source, mail, news and chat client for Windows based on Mozilla Thunderbird from the Pale Moon developer.

It is an optimized and reconfigured re-build of Mozilla Thunderbird ESR. 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.
