Program: Tor browser
License: Open Source
Description: Tor Browser lets you use Tor on Microsoft Windows, Apple MacOS, or GNU/Linux without needing to install any software. It can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained (portable).
Other: It's a portable version by itself and based on firefox. But I'm looking to launch it from portable apps platform.
