Microsoft has launched a reincarnation of MSN Toolbar in beta form, codenamed Salsa.
The toolbar is powered by Silverlight, which adds an extra dimension to the features on offer. This enables the drop-down MSN chanel previews, showing the latest content from within the MSN portal without requiring the user to move from the internet page they are currently browsing. From the same preview pane users can also chose to search that part of the site, which brings us onto the other main feature, Live Search. There's a breaking news feature, bringing the latest news direct to your browser.
