Pressure.
Hot gasses try to expand and create pressure.
Very rapid burning of a chemical mixture creates hot gasses.
A fuse burns down into the inside of a firecracker and starts an extremely combustible chemical mixture burning.
A match lights a fuse.
A person strikes a match causing it to light.
A person decides: "I think I will light a firecracker".
You could pick any of of these causative agents as the thing that makes a firecracker explode:
An Idea
A person
A match
A fuse
A combustible chemical mixture
A rapid burning of a chemical mixture
Hot expanding gas
Pressure
It all depends upon where you want to draw your system boundary.

firecrackers contain gunpowder which when lit burned. The burning of the gunpowder creates heat which in turn makes the pressure inside the the firecracker to increase. This pressure pushes out the container of the firecracker. When the container breaks the pressure pushes the air around the container that creates the exploding sound.

a fire cracker explodes due to pressure built up inside of the firecrackers structure. if shake a soda can and throw it on the ground it to will explode. the pressure is much the same except created differently. the slower the powder burns the more pressure builds. greater the explosive force.

A firecracker is a cardboard tube filled with gunpowder. When the powder is ignited by the fuse, it burns very rapidly, turning into a hot gas under high pressure. This pressure bursts the tube open and this explosion is the sound you hear.

The rapid chemical reaction of combustion which creates a volume of gas larger then it's container.
Or black magic, I'm not really sure.
