A Thunderbird-based mail, news and chat client

FossaMail is a Thunderbird-based mail, news and chat client from the developers of the Pale Moon browser.

The program features Pale Moon-like compiler optimizations "geared towards an as stable and smooth operation of the client as possible", and also uses the Pale Moon browser core as its back end.

FossaMail looks and feels just like Thunderbird, and it should run all Thunderbird (v24/25b era) add-ons and plugins.

FossaMail stores its data in a custom location (%APPDATA%\FossaMail), allowing you to install and run FossaMail and Thunderbird on the same system.

There's also an optional calendar, Lightning, available from the developer's site.

What's new in v38? (changelog)

- This version bumps the application version to 38.0 for reasons of add-on compatibility.
- The only other change is no longer directly relying on for extension updates


FossaMail is a straightforward email client with plenty of worthwhile features. We're unsure if it's significantly better than Thunderbird, but you can install and run the programs together, so it's easy enough to compare the two.

WhatsApp Messenger 2.17.7

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.
