Browser Tip of the Day: Make Firefox's RSS icon work with other newsreaders

Firefox has a feature called Live Bookmarks, whereby a colorful little icon pops up in the status bar whenever Firefox detects an RSS feed, and you can use it to cause the feed's latest headlines to appear in a special folder in your bookmarks. It's a cool feature, and could probably be a Browser Tip all by itself, but I never use it. However, LiveLines, an extension by Gomyoung Kim, makes the little RSS icon that much more useful by turning it into a Subscribe button for Bloglines, NewsGator Online, Sage, or a handful of other RSS readers (most of them web-based).
