GoogAzon is a FireFox add on to simplify your Amazon and Ebay search. Display your searches for videos, music, games, electronics and much more every time you use Google, Yahoo or MSN Live search. Once installed, any time you search for an item on Google, you'll also see the top search result for your query from Amazon. If a single product listing isn't good enough, just click the "see top 10 items" button and a list of 10 items from Amazon will drop down.
