A couple years ago I was doing something foolish with gasoline and trying to burn a pile of unwated wood. (I live in an area where tree limbs randomly falling and getting in the way is a common occurance for anyone)
That day I poured out gasoline on a wood pile, and got a little on my bare feet. I was wearing flip-flops.
So, when I lit the gasoline-soaked wood pile, my feet also became directly on fire as well. Also all the gasoline on the wood exploded into a fireball, and my hair caught on fire, too.
Thankfully, I had instruction from being in the boy scouts as a kid, and as soon as I knew I was on fire, 'I stopped, dropped, and rolled'; immediately getting down on the ground and rolling all my skin against ground, so it would snuff out the flames.
Though my skin was directly on fire, I got away with burns that completely healed.
It occurs to me that not all have this intruction. I'm warning you all that the last thing you want to do while on fire, is panic and run.
Oxygen is what feeds fire. Moving fast while on fire will only fan the flames and make it burn hotter.
The first thing you need to do when you notice an unwanted fire on yourself is snuff out the flames with physical force.
If it's large, quickly drop yourself and roll your body against the ground. If it's extremely small, like a lighter flame, don't be afraid to swat it out with your hands, as if you're swatting a mosquito.

Extra: If you see someone choking, perform the Heimlich maneuver, wrapping your arms around their stomach and squeezing as hard as you can, like so:

And if you're bitten by something venomous, or bleeding profusely from a limb, you'll want to take anything you can wrap tightly around the limb before the wound, like a scarf, a tie, or a long sock, and tie it tight into a tourniquet:
