Unity3d not working OnCollisionEnter2D?

Question

C++ / C#

void OnCollisionEnter2D(Collision2D collision)
{
if(collision.gameObject.name=="Fire")
    {
        Destroy(collision.gameObject);

Answer 1

Everything is working. You have problems. Either there are no colliders, or they are triggers, or they are not 2d, or something else.
