Single most useful addon for Firefox 3

I have been fiddling with various addons for firefox 3, but found Feedly to be the most awesome.

It is basically a start page/feed reader, but looks much much better than iGoogle or even Google Reader!

I have not yet tried all the features, but the UI is very good; it has a newspaper kind of interface, but it also has so many keyboard shortcuts like the Google Reader.

For most of the blogs, it shows the comments as well on the same page.

And the coolest thing is it is directly linked to Google Reader, so you need not subscribe to all your feeds again.

Give it a try, I am sure you will find it engaging.
