Does oxygen make something burn?

No it doesn't make something burn. But if something is already burning, it supports the burning. In the fire triangle, which is what makes a fire, it says that you need fuel, oxygen, and something else, that I tend to forget. So, technically, oxygen does make something burn, because you need that oxygen to help it and if you don't have that then it won't burn. So, I say yes, it does.

What is in oxygen that makes the fire burn better?

Oxygen itself. Oxygen is one of the elements necessary for a fire to burn, and the increased presence of it helps to further fuel the fire.
