Sage is a basic RSS feed and news aggregator for Firefox. Its no-nonsense approach and ease of use will appeal to all user levels.
The extension is meshed with Firefox's sidebar. It's very easy to navigate, with buttons for checking and searching feeds, and two view panels. The top panel displays each feed that you're subscribed to, and the bottom panel displays the specific feed headlines. The Options menu gives you display options, and lets you manage your feeds. Copying and pasting feed URLs to add them to our list of feeds is as easy as it should be. Clicking each feed link introduced the individual feed headlines in the lower panel, and also displayed the feed Web site in the browser window. The program lets you manage individual headlines, marking them as read or unread. If you'd rather not interrupt your browsing, you can just hover your mouse over each headline, and a window pops up with the first few sentences of the story.
This free Firefox extension required little effort to understand, and will have you viewing your feeds in no time. Highly recommended to those who want a feed reader that's rolled into their browser, but not a Web app.
