Police Scotland received 144 fireworks-related calls on Saturday night – down on 160 on 31 October last year.
Fireworks were thrown at people, buildings and vehicles in some parts of Scotland on Halloween.
Officers said in general there was “outstanding behaviour and co-operation” around the country but were working to identify to those responsible for disorder.
Firework Control Zones (FCZs) – where it is an offence to set off fireworks – are in place in 14 areas in Edinburgh and four in Glasgow until early November, and dispersal zones are in force in some places.
On Halloween there were reports of fireworks lit in the street and some thrown at members of the public in Glasgow, Tranent in East Lothian and Bonnyrigg in Midlothian.
Police said no officers were injured and inquiries to identify those involved were ongoing.
