Amazon testing new design

It looks like Amazon is testing a new design–I see it from only FireFox, likely there is a cookie set for the new design. The big deal with the design is that is pretty much does away with tabs (see screenshots below). I think it works well because there were just too many tabs before. Amazon popularized the use of tabs which makes this change ironic.

Amazon’s A9 websearch is also shown right at the top.

Between screen caps 1 and 2 all I did was move my mouse to the second tab, "See all 31 product categories." I did not click–it’s on the mouse over state.
