feed-firefox-demon
Feed Your Reader allows you to use the RSS Autodiscovery in Firefox (1.0PR) to launch external aggregators, such as Nick Bradbury’s FeedDemon. ... FYR replaces the functionality of the built in RSS icon, if you wish to add a live bookmark, hold down the shift key when you select your feed.
That’s so cool! I’ve added it, what a great way to make Firefox and Feeddemon work together! 
And shush, you people who noticed I posted two posts about Firefox in a row. LOL!
