Whilst I agree with the above, focussing on the correct touchdown point will more often than not lead to firm landings. At least, that is my personal experience. I changed onto the Airbus with quite a few hours of Boeing time under my belt, but for the first few days of line training I struggled to land the aircraft decently because I was so focussed on the correct touchdown point: the training flights were out of the shortest runway in the network!
My landings and my confidence improved dramatically when I landed on a 3000m runway. Not because I floated the aircraft, which I did not, but because I wasn't fixated on the TD-point and focussed on other visual cues to fine tune the landing!
