An Adelaide home has been firebombed in an attack overnight.
A molotov cocktail was thrown through the front window of the home at 11.40pm.
A 36-year-old man inside the home suffered from minor burns to his arms but managed to extinguish the fire.

Neighbours said the attack left them speechless and called the attack random, but police say the house was potentially targeted.
"It's dangerous a molotov cocktail could burn the whole house down if you don't know [that it's there]," one man said.
"I'm speechless...I never knew that would happen [here]."
The home wasn't burnt down, but the window was smashed in.
Emergency services attended the scene and seized the remains of the molotov cocktail to conduct forensic testing.
