Getting RSS Feeds on Mozilla Firefox

There are 2 ways that I know of:

1. Use Mozilla Firefox's Live Bookmarks function.

Whether it’s news from CNN and the BBC, or posts on your friend’s blog, the Web is updated continually. Firefox’s Live Bookmarks feature automatically keeps track of these updates for you, so you always know when new content has been added to your favorite sites.

With Live Bookmarks, the content comes to you. Instead of constantly checking Web pages for changes and additions, a Live Bookmark delivers updates to you as soon as they are available.

2. Use Firefox add-ons for RSS. The one I'm using now is Sage.
