The ManRoulette website uses Flash to connect with the webcam. The Mac needs to have the latest version of Flash Player installed (See links below) and permission has to be granted for the website to access the camera.
No because its a view only site. It needs to physically act on your computer and on its server its not possible. It can make it run slower. Try rebooting your PC. This will help x
