No. Fire extinguishers use a dry powder to smother the fire. Firefighters use two types of foam that can be broken down into more categories. A class "A" foam is actually a type of soap. It is used to break up water tension so that water can seep into the ground and/or fuel better. A class "B" foam is used to make a blanket that smothers gasoline or diesel type fires.
Why gas helps to make the foam that firefighters use?
AFFF or aqueous fire fighting foam is a chemical agent that is added to water usually at a rate of about 300:1 (300gal water for 1gal foam concentrate) this mixture is then mixed with the outside air as it exits the nozzle and creates a blanket of foam that suffocates the fire.

Which is the gas that helps to make foam that firefighters use?
Air is the gas most commonly used to create the foam that firefighters use. Most commonly, the foam is generated by adding a small amount (1%-5%) of foaming agent into the water flow coming from the fire engine. This is done by either injecting it into the water stream with a small metering pump, or with a foam eductor which draws the foam into the water stream using a venturi. A foam play pipe, or Foam nozzle is used on the end of the water line which is designed to draw air into the stream of water, and creates the foam. More recently air compressors (CAFS - Compressed Air Foam System) are being added to some newer fire apparatus which injects air directly into the water stream. This allows for even less water to be used in firefighting, and produces a more consistant foam.
How can you make foam?
Foam can be made by introducing air into a liquid. This can be done by whisking, blending, or using a foam dispenser. The proteins and surfactants in the liquid help stabilize the air bubbles to create the foam.
