I enjoy fireworks, my dogs don't. I couldn't afford to buy fireworks big enough or in quantity to enjoy, so personally I am in favour of restricting the sale of fireworks to licensed events. afaik it is still ileagal to discharge a firework in a public place or outside of certain dates/ times. Obviously this isn't enforced, but they are certainly a bigger nuisance now that every celebration/ holiday seems to attract them. 20 years ago they could only be bought for a couple of weeks around 5th Nov.
You can no longer buy the components of gunpowder without a license, yet fireworks can be bought by any muppett, seems strange to me.
I would also say there is a trend toward more and larger 'rocket' type fireworks, I wonder how happy the 'don't ban them brigade' would be if the 1lb pointed carcass of one let off from a neighbours garden landed on their head/ car roof/ through their greenhouse roof?
