What? What’s that you say?
Yes, all you Tool Time Friday Freaks – you can, yes you can, yes you can, can can!
Here’s the scoop.
The Feed Sidebar is an extension for Firefox that displays the items from your Live Bookmarks in the sidebar. It is intended to be a lightweight extension of the RSS capabilities already included in Firefox, not a completely new feed management system.

Installing the Feed Sidebar will add a new sidebar to Firefox that, when opened, will display the unread items from the feeds that you have bookmarked in Firefox. Clicking on an item will show a preview in the bottom of the sidebar, and double- or middle-clicking will open the item in the browser and remove it from the sidebar. The Feed Sidebar will also notify you of broken or unavailable feeds, something which I wish Firefox did in a more obvious manner.
You can choose to have the sidebar continue displaying items you’ve already read. If you do, these items will appear grayed out. If all of the items in a feed have been read, the feed title will be grayed out as well.
The Feed Sidebar will continue to check for new items when the sidebar is closed and will notify you when new items are found. As of version 3.0, it also has offline support, so you can read all of your feeds even if you have no Internet connection.
