Yahoo unveils a “sneak peek” of a new product that aims to bridge the gap between your web browser and desktop—BrowserPlus, a desktop utility that enables richer browser interaction, like drag and drop file uploads. The BrowserPlus utility is available for Windows and Mac at the moment and works with Firefox, Safari, and Internet Explorer 7. There are only three demo applications that use BrowserPlus: a Flickr drap-and-drop image uploader, an IRC chat client, and for the web monkeys, a JSON inspector. In short, BrowserPlus is more proof-of-concept than anything else. But, with Google ramping up Gears, Firefox 3 building in offline webapp support, and Yahoo busting out BrowserPlus, looks like your web browser and your desktop are going to be more than just friends in the coming months. The BrowserPlus sneak preview is a free download for Mac and Windows.
