Firefox Extensions: Sage RSS Feed Reader.
I have over dozens of blogs that I enjoy reading everyday. It can be a pain when I actually browse them one by one, thankfully we have something called RSS. It allows us to fetch excerpt of articles from different sites together, skimming through them, and click on your desired article title to view the full content. Some bloggers/webmasters prefer to deliver their feeds in full, some in excerpt.
Now, I’m going to recommend another Firefox extension, Sage. I like firefox extensions because most of them are very light weight. This sage extension is only 135kb. As usual, install it and restart your firefox browser. There is more to learn.
In order trigger/use Sage in your firefox, look at the screenshot below, it’s just left to your address bar.

Or you can find it in Tools > Sage.
All small screenshot of it.

One thing I like about Sage is, it’s compatible with your firefox bookmark. Just group all your feed pages in one bookmark folder, then select that folder in Sage. It’s in the left panel, Options > Settings > Select Feed Folder. Please note that normal bookmarks will not work with Sage, you need to bookmark the “feed page” of particular website. You will have one bookmark folder called “Sage Feeds” by default.
Feed page can be reached by clicking on the RSS button at the end of the address bar, if that particular site is RSS enabled.

Thoughtful webmaster will have the link somewhere obvious to remind the readers. Like mine located at the sidebar.

Try using Wizz RSS News Reader! It’s also a Firefox extension and it’s WAY more powerful than Sage – https://addons.mozilla.org/firefox/424/
Thanks for the information Bender, I’ll take a look later.
I agree – Sage is great. Just the right tradeoff off of functionality/simplicity.
I do a lot of web-based company research for investment purposes. I’d strongly suggest combining Sage with another Firefox add-on called Gnosis. Sage manages the feeds – and Gnosis finds the people, companies, geographies, etc within those feeds automatically. They work great together.
