Flock
I’ve just installed Flock. It is a firefox based browser with added functionality. I’m using it now to write this blog item… It has some other cool stuff like online bookmarks (through del.icio.us), a very nice rss feed reader (although not perfect yet) and a flickr integration.
It is still a pre-beta release, they call it the developers release, but for that status it works very, very well. And since it is based on firefox you will have no problems reading your favorite websites.
