Is that the solution?

if (player.cuurentFrame == 3 && player.playerfire.currentFrame >= 6 && player.playerfire.currentFrame <= 8 && player.scaleX == -1)

The usual response for that error is that the object in question does not exist on the timeline in the same frame where the code is written. Since playerfire is inside player, you'll need to be sure that player in available at the frame where the code is and that playerfire is available inside player.
