Firefox supports reading RSS feeds, both "out-of-the-box" through the
live bookmark feature, and through using extensions.
To use the live bookmark feature is dead simple:
You'll see an icon
in the Firefox status bar, near the bottom right corner (depending what extensions you're running, they may move it somewhat). Clicking on this icon will give you a popup list of available feeds from the page you're reading. I've chosen to advertise a variety of different feeds from this forum, in order to give a lot of choices to users.
When you select one, you'll get a normal "Add Bookmark" dialog that allows you to file the feed in your bookmarks, so that you can then access it from the bookmark menu or sidebar.
Once you've added a feed to your bookmarks, you can easily choose the "open in tabs" option, which will use the tabbed browsing feature in Firefox (this works on any bookmark folder, by the way) to open all the pages in their own tabs.
Working with RSS this way gives you a quick way to stay current on site information as it changes.
