RSS Feeds Toolbar for IE is an add-on for Internet Explorer, that integrates RSS feed headlines into the IE toolbar. The headlines are continuously updated at a configurable time interval and a button in the toolbar launches the full article associated with the selected feed item. The latest headline is always on top and displayed directly in the toolbar, while previous headlines can be selected from the drop menu. Not a full-featured RSS reader, but a very convenient way to keep track of several news sources from within your browser.
