A buff to CFL3 and thermite (and mabye other fire chems)

[Berrik]

If you are on fire because of CLF3 or thermite, using a fire extinguisher should not help you at all. In the case of CLF3 specifically, in fact, quite the contrary, since it's supposed to react explosively with firefighting foam.

Saw a guy earlier using a CLF3 flamethrower on the blob and just using a fire extinguisher to immediately remove the fire from his body when he set himself on fire.
