FossaMail is an alternative version of the Mozilla Thunderbird mail andnews client, and based on the Pale Moon browser core.

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-powered products.
  • 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.

What's New:

This is a security and stability release, updating the client's back-end to Pale Moon 25-LTS 25.9.1.
This incorporates all relevant core security/stability updates from the latest Pale Moon version, as well as a fix for a potential problem when composing using an LDAP-based address book.

  • This release fixes an additional issue with resuming from stand-by.
  • Updated the Pale Moon back-end to the latest release version (25.3.1)
  • Cleaned up code left over from the crashreporter and sunbird
  • Added x86/x64 indicator to the about box
  • Added Windows 10 OS support in manifests
  • Removed LDAP Autocomplete code no longer in use
