Sage-Like Extension

an RSS extension for Firefox Portable

The Sage Extension works within Mozilla Firefox - Portable Edition and gives you access to a lightweight RSS reader using much of the built-in functionality of Firefox. It supports RSS and Atom feeds, feed discovery, customizable feed layouts and more. And, since it uses Firefox for many of its functions, it's a very small download.
