The question that a lot of people bring up when they're talking about open source extensions and plug-ins is that "What happens when a new version of X comes out, will my favorite plug-in for it work?"

In some cases, especially with Wordpress, unfortunately the answer is often No.

But Firefox has a dedicated community that does a really good job of porting over the most popular extensions to new versions of the browser. This makes not only the community strong, but the browser and the Firefox initiative itself stronger.

Sage is an extension that basically replicates a desktop RSS/Atom reader, but it's really lightweight and integrates with Firefox well. That's what Firefox does well. Seamless experience with software and the web.

The new version that works with Firefox 3 is called "Sage-Too". Kind of like Teen Wolf Too, but better. And with no wolves. And without Jason Bateman. He was great in Juno and Arrested Development, but Teen Wolf was not his shining moment.

We digress.

Here's a Sage-Two feature rundown:

• Reads RSS (2.0, 1.0, 0.9x) and Atom feeds
• Newspaper feed rendering customizable via style sheets
• Feed Discovery
• Integrates with Firefox's bookmark storage and Live Bookmarks
• Imports and exports OPML feed lists
• Technorati and RSS search engine integration
• Support for a number of locales: Argentine Spanish, Catalan, Chinese, Czech, Danish, Dutch, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Serbian, Slovenian, Spanish, and Swedish
• Simple, one step install / uninstall
