Fireworks in this game are basically someone people buy to amuze themselves or other people during bordum. Mainly u see rich people buying them alot just to show off or the resellers, like my friend, who will buy them in stacks and sell them for 500-1000 gil a piece slowing makes 50x more then what he payed for.
I just made a video of me using one of these in preperation for a Linkshell fireworks display for our 6 month anniversary. So if you want to see what these do you can go to http://www.bregan.info/videos/wmv/cracker.wmv
