Is fire weightless? Why doesn’t it float away into the atmosphere?

Oxygen and Nitrogen make up a significant part of the atmosphere. Fire always stretches upwards, assuming no wind, leading me to believe it’s less dense than air. Oxygen is highly flammable. That should be everything fire needs to sustain itself while flying away into the sky.

Fire needs oxygen, fuel and heat. Oxygen is not flamable, it is essential for fire but you need additional fuel.
