If you haven't already can you send a link to where you got that image off the web. In this case, I suspect that to create the screenshot the person just updated the stylesheet (which is really easy to do in modern browsers) and that no tool exists as shown, if there is a download it is likely malware but something we can look into. With all suspicions like these we do take them seriously so if you can send the link through to support we can take a look.
