In this talk, I discuss three recent developments in our understanding of form factors of local operators in planar N=4 super-Yang-Mills theory. First, I discuss how the so-called form factor operator product expansion (FFOPE) allows us to determine form factors of the chiral part of the stress tensor supermultiplet at any value of the coupling in an expansion around the (multi)collinear limit. Second, I discuss how we can use the FFOPE data to bootstrap the corresponding three-point form factor for general kinematics up to eight-loop order via its symbol. Third, I discuss a new weak-weak duality by which the three-point form factor is related to the six-point amplitude in the same theory.
