The most common type of portable foam extinguishers contains fluorosurfactants.
There are other which also contains proteins or compressed air.

Fire extinguishers commonly contain water under pressure, compressed carbon dioxide, foam, or specialized dry chemicals, depending on the type of fire they are designed to put out.
A fire extinguisher stops a combustion reaction by removing one or more of the essential components of fire: heat, fuel, or oxygen. Different types of extinguishers work through various mechanisms; for example, water extinguishers cool the fire by absorbing heat, while foam extinguishers smother the flames, cutting off the oxygen supply. Dry chemical extinguishers interrupt the chemical reaction itself, effectively disrupting the combustion process. By targeting these elements, fire extinguishers effectively halt the fire's ability to sustain itself.
Carbon Dioxide is the most common gas in fire extinguishers.
Depending on the type of fire there are different option. Water, CAFS(Compressed Air Foam System) or a variety of fire extinguishers
aqueous film forming foam (AFFF), if you have one, although CO2 or dry-chemical fire extinguishers are also rated for combustible liquids, such as diesel.

"foam" fire extinguishers are made for hydrocarbon fires...i.e: gasoline, diesel, etc. These fires are considered class "b" (flammable liquids), and are mostly used by professionals and in commercial and industrial settings. These extinguishers are charged with anther AFFF, FFFP, or AR-AFFF, however, these class of extinguishers are only rated class A & B fires and are hazardous to the environment, humans and animals in addition to being very corrosive.
Only fairly small ones as they run out of the foam fairly fast. They are to be used when a fire is first detected. Below is an article about fire extinguishers.
Some fire extinguishers use dry chemicals and some use a foam to extinguish flames. Some fire extinguishers actually still use water, but they're only for use on smaller fires. Others use a dry chemical, mostly sodium bicarbonate, or Carbon Dioxide.
