In a large saucepan, combine the oil and popcorn, cover and cook over moderate heat until it starts to pop. Shake the pan and cook until the corn stops popping.
Transfer the hot popcorn to a large bowl. Sprinkle with the paprika and sugar and toss well. Drizzle with the butter and toss, adding the furikake and rice crackers. Season with salt, toss again and serve.
