Why does the density of carbon dioxide as compared to air make the carbon dioxide useful as a fire extinguisher?

Put simply, fire requires three things to burn: a fuel, heat and oxygen. The fuel is whatever the fire is burning, and this may be something like wood, gasoline, paper, bedsheets, yeah you get the point. It creates its own heat, so that leaves one more: oxygen.

Oxygen is present in the atmosphere, the atmosphere is all around the fire. Oxygen is also a relatively light compared to carbon dioxide, because oxygen is O2 and carbon dioxide has an extra carbon atom in the molecule, CO2. When you release a lot of carbon dioxide, it instantaneously displaces the O2 in the atmosphere, because less dense objects like oxygen will rise. With no oxygen around, the fire extinguishes.

Why would frost form on the outside of a fire extinguisher?

When looking at this use the equation PV = nRT. From this you can see that temperature and pressure are proportional to one another. So if your temperature increases for the same volume and number of moles your pressure must also increase. When you use a fire extinguisher you rapidly decrease the pressure inside the container which causes the temperature to decrease. The frost you see is water vapor from the air freezing when it comes into contact with the cold outside of the extinguisher.
