Chrome: Firefox's Live Bookmarks show RSS headlines right from the bookmark bar. Chrome lacks this built-in convenience, but Extension RSS Live Links adds it in, saving you the trip to Google Reader just for a few headlines.
Like Firefox's Live Bookmarks feature, RSS Live Links allows you to subscribe to multiple feeds, view them in a menu-style popup, click on an individual one to show a list of recent headlines, and then click on those headlines to navigate to the full article. You can also put it in an actual bookmark folder on your bookmark bar, like the original Firefox feature, if you prefer that instead of next to your address bar.
There are also a ton of other options, like customising which feeds are opened by default, when and how you receive notifications of new articles, and even the colour of read and unread items. This extension is probably a Godsend for those that loved this feature in Firefox and want to switch to Chrome, but even if you had never used Live Bookmarks before, it's definitely worth checking out, especially if you don't want to open up a new app or page every time you want to just check the headlines. It's a free download, works wherever Chrome does.
