eBay and Yahoo get together and build a toolbar
Last year eBay entered into an advertising agreement with Yahoo, part of that agreement was to build a co-branded toolbar. It's now available.
The new eBay toolbar uses both Yahoo and eBay features to power it. With it users can search for items on eBay or Half.com, and search with Yahoo using Yahoo Local, Yahoo Video and Yahoo Answers among others. The toolbar also has one click access to Yahoo Mail, and gives direct access to eBay.com. Complete with account guard to protect auction accounts and eBay auction Alerts.
The eBay toolbar featuring Yahoo is currently available for Internet Explorer Windows users only, with a Firefox version in development.
