"firework powder" is usually gun powder or blackpowder... So yes both of these options can be used in cannons, but don't mix blackpowder with gun powder since they burn at different rates.
Gunpowder- both the original black powder, and today's smokeless powder, is a combination of a fuel and an oxidizer to make that fuel burn. It must have both to work. One without the other is useless.
there are several typed of powder the most common are black powder and smokeless powder. black powder is very corrosive and burns slower com paired to smokeless and just by the name there acepinaly more smoke were as smokeless gun powder is stronger and faster and cleaner.
