No, slower. Light travels fastest in a vacuum. Anything transparent that light can pass through slows it down somewhat. Diamond crystal slows it down notably, which is part of what causes the "fire" in a diamond.
Why can you hear a fire engine coming around a street corner before you can see it.?
There are two reasons why we can see a plane in the air before we hear it. The first reason is the fact that light moves faster than sound. Everything we see is the result of light reflecting off of an object and into our eyes, producing an image. Second, the plane might be too far. So, with that in mind, we might not even be able to hear the plane in the first place.
Can you fight a fire with liquid helium?
If you have enough liquid helium, it might smother the fire or cool the combusting materials that are supporting the fire so much that they are below their kindling temperature. However, this would be a very impractical fire fighting technique compared with using solid or liquid carbon dioxide, because carbon dioxide gas is denser than air while helium gas is much less dense than air. Furthermore, liquid helium is expensive and only rarely if ever available when one needs to fight a fire!Note that the boiling point of helium is 4.22 K, −268.93 °C, −452.07 °F. From a practical standpoint it would be nearly impossible to maintain such extreme cryogenic conditions anywhere in the vicinity of a fire!

Why do you use a group of twigs instead of a log when starting a fire?
The smaller and thinner something is, the easier it is too ignite. For instance, a blade of dry grass will burn up in less than a second from a spark. But put a lighter too a tree, and you will get nothing accomplished. The usual parts of a fire are, 1. Tinder. This is what lights quickly, and goes out quickly. And you will put the flame to it initially. Usually dried grass, newspaper, dry leaves, etc. 2. Kindling. Kindling are the small sticks that the tinder lights. They light pretty easily, and go out pretty quickly. 3. Fuel. This is the main part of a fire. You will start off putting on small sticks and eventually logs.

It is difficult to ignite wood or coal using a lit match. The match would burn down and singe your fingers long before the wood or coal would light. Using kindling of dry wood shaving, or thin twigs and dry grass, or paper (with or without kerosene), will ignite with one match and burn long enough to light a fire of wood or coal.
