Live Bookmarks is a new technology in Firefox that lets you view RSS news and blog headlines in the bookmarks toolbar or bookmarks menu. With one glance, quickly see the latest headlines from your favorite sites.
RSS (an acronym for "Rich Site Summary" and later coined "Really Simple Syndication") is a way for web sites to summarize their content, such as news articles, to make it available in a different view.

Jay say: Consequently, this site has RSS, I totally knew that...um, really.
