"Amazon Mini Shop is a Firefox add-on which gives you the ability to search Amazon.com, as well its various region-specific sites, right from your browser's sidebar. You can quickly perform a keyword search within one of the site's dozens of categories without leaving the current Web page that you are on. Results contain each item's title, thumbnail image, and current price, and are displayed within the sidebar itself. This add-on also lets you add specific searches as an RSS live Firefox bookmark."
"The Amazon Sidebar lets users of Internet Explorer, Opera, Seamonkey, or Firefox search Amazon sites from the sidebar. It also includes a link so you can save searches in RSS format."
