Lunascape software (version 6.12.1) is a web browser that offers three rendering engines, including Trident (used by Internet Explorer), Gecko (used by Firefox), and WebKit (used by Google Chrome and Safari). This allows users to switch between engines to optimize their browsing experience. It also includes a customizable interface, mouse gestures, and a built-in RSS reader. Additionally, Lunascape offers a feature called "Orion Sync," which allows users to synchronize their browsing data across multiple devices.
