With this option activated, only one instance of Konqueror will exist in the memory of your computer at any moment, no matter how many browsing windows you open, thus reducing resource requirements. Be aware that this also means that, if something goes wrong, all your browsing windows will be closed simultaneously.
Con esta opción activada, só existirá en memoria unha sesión de Konqueror en cada momento, independentemente do número de fiestras abertas, o que reduce o consumo de recursos. Teña en conta que isto significa que, se algo vai mal, todas as fiestras de navegación serán pechadas simultaneamente.
