The smaller size of oxygen means the lone pairs of one oxygen are close to the lone pairs of another, and they repel. Since Sulfur is larger, the lone pairs are further away and therefore repel less. The repulsion is what is weakening the bond of O-O compared to S-S. Similarly, the bond of N-N is weakened by repulsion, but not as much as O-O.
 
Also
stongest bond is F-F
