The following is a compilation of tips i found on several places on the internet,i didnt test all of em so your mileage may vary 
Roll a sausage of cotton wool and dip it into molten candlewax,good firestarter.
Roll some cotton wool on a match and dip it into molten candlewax (keep the head clean) to make a firestarter.
Dry oakleaves burn fast and are an easy way to spread a flame in your starting fire.
Digging a small depression beneath your firewood makes sure theres sufficient airflow.
Treeraisin,candlewax,vaseline and shoepolish dabbed onto a bit of tinder make it burn longer and hotter.
Pencilsharpeners can be used to make fine tinder from small sticks.
Think outside of the box,peppermints,chips (the edible crunchy type) etc burn realy good (high fat or oil content)
Birchbark,great tinder and no need to cut a tree for it.
Cattail (Typha Latifolia) gives a nice down,good for spark type firestarting.
Batteries and steelwool,just touch the battery to it and it will start to burn (most common type named is the 9 volts brick type)
Steelwool catches sparks good.
When using matches or lighters light a candle first and light your fire with the candle.
Dried orange peels (skins?) burn good.
Woodshavings with oil make good tinder also waterproof.
30 centimeters of gardenhose,doesnt take a lot of room and handy to blow the fire back to life.
Always carry one or two spare disposable lighters,theyre cheap and small so theres no excuse to not have the backup.
Theres tons of things i missed so feel free to add a few of your own.
