Websites can make use of JavaScript to create menus, animations, sounds and other features to provide an interactive multimedia experience for users. The Firefox, Chrome and Safari Web browsers each require a different process to enable JavaScript on the Mac. After you enable JavaScript, you may need to restart your browser if the changes don't take effect immediately. By enabling JavaScript, you increase your Mac's vulnerability to threats including viruses and to outside parties that monitor your activity.
