RSS Bleg

Dear LJ Brain Trust, I need your help.

I'm looking for alternatives to the Safari Tiger browser and getting familiar with the capabilities of Firefox. Firefox is great! But there's just one problem.

The one thing Safari does really well is its RSS feature. Safari doesn't just offer individual RSS feeds - it combines them on a single screen. So with a single click I can read the latest entries in The Belmont Club, The Counterterrorism Blog, Iraq the Model, Tammy Bruce, and a dozen other sources ... all at one time. This is way better than Firefox's live bookmarks.

So the question is: Is there any way to replicate this function outside of Safari? I've tried everything I can think of with Firefox but it's not getting me what I want. I opened an account with del.icio.us and uploaded my Safari bookmarks, but that won't give me a consolidated feed either.

Any ideas, tech geeks?
