Google has announced a new Chrome Extension and Google Toolbarfeature called Google Related, which suggests new content relevant to the page you’re currently viewing. The extension offers many kinds of suggestions, including Web pages, shopping, maps and Google Places results. Google Related displays a toolbar at the bottom of the browser window, and the suggestions pop up when the mouse hovers over them. If you like a suggestion, there’s a built in +1 button.
In order to provide these suggestions, Google obviously has to track your browser history. The Google Relatedand Google Toolbar privacy notices describe how the information is used and stored. Installing browser extensions or plug-ins is voluntary, of course, and they can be disabled or uninstalled anytime.
