Chrome only: Google Chrome extension Foxish Live RSS mimics Firefox's Live Bookmarks feature by creating folders on your bookmarks bar that update automatically from your favourite RSS feeds.
The extension isn't perfect, but it's a step in the right direction for having live bookmarks that work in Chrome — you'll have to head to the options page to manually add your favourite RSS feeds and you can't change any other options yet. Updates happen every five minutes, and the developer mentions that Chrome has some limitations on how many feeds you can use at a time — in our testing, it worked perfectly with a handful of subscriptions. Foxish Live RSS is a free download, works anywhere Google Chrome extensions do.
