Simple addon for Google Chrome

The plug-in would show an icon in the browser's toolbar, next to the address bar. On each page load, it would send a REST request to a server with the current URL and will receive back an empty response or another URL. If there is a URL in the response, the icon would change color and a popup will appear. Clicking on that popup would send the user to the returned URL in a new tab. Only bidders with previous experience in creating Chrome plugins will be considered! I will expect to see a list of similar projects you have completed.
