This will probably come to many of you as old news. If it does, I think you’ll agree it still deserves attention. Here’s my take on infoRSS for Firefox.
infoRSS for Firefox

I started using this extension two weeks ago and I’ve had it hard at work for a good 13 hours a day since. The infoRSS extension creates a scroller that sits in your status bar and gives you the feeds of your choosing as they update. You can switch through feeds with the click of a button that sits next to the scroller. You can also add the feed of any page that has one with the single tap of the mouse. The status bar includes a small menu of icons that help you navigate through the options with ease.
The plugin comes with some freedom in customizing the way the feed scroller functions. This is a huge bonus in my view. You can choose to have the feeds scroll, and if you’re not a fan of the side to side view you can have them fade in and out instead. You can also choose to have the feeds come in random or run them as a loop. And you can pick the frequency of the updates.
The following is a full list of infoRSS features.
