Upon installation you can opt out of the Yahoo search. It's lightweight, it adds favorite top sites (which you can edit), plus it adds beautiful photos from Flickr. The only thing I don't like is that the maximum number of sites you can add is nine. Ignore the reviews from 3-4 years ago, it doesn't add a "toolbar".

ITS VERY NICE &SUPPORT

I love the pics it brings about and it's a new surprise everytime I open a new Tab. In the world where we are bombarded with news and info from everywhere, these silent beautiful pics are a great breather before we go to a website.
