Do extension cords use electricity when plugged in but turned off?

While extension cords themselves do not draw vampire power, if an electronic device is plugged into the cord, it may draw power even when it is off. Additionally, there are fire hazards associated with the prolonged use of extension cords, so it is better to use them only temporarily.

Should you unplug extension cords when not in use?
