Immediately after Water Temple, play Sun's Song until it's at sunrise. Then shoot the sun and fire arrows will fall onto the platform.
There is no shop that sells fire arrows after you get the fire arrows from Snowhead Temple, all you need is your Magic energy meter filled up and some regular arrows, and you can use fire arrows.
Leave them alone
depends on the game. In ocarina of time you find the fire arrows at lake hylia, the ice in the gerudo training grounds. In wind waker the queen fairy gives them to you. In majora's mask you find fire in the snowhead temple and the ice arrows at the great bay temple
water temple
By defeating the mini-boss in Snow Peak Temple you are rewarded the Fire Arrows
They come with the bow, which can be found in the forest temple. Other arrows: Fire Arrows (go to lake hylia and fire an arrow at the sun as it rises), Ice Arrows(complete the gerudo training ground), and Light Arrows(given to you before entering ganon's castle and beating the game).
you have to beat the fire temple.
The fire arrows and to get in the well as a kid get in front of the well and play song of storms and the water will sink and you can go in Hope that helped :)
Shoot arrows <------- this idiot doesn't realise that you don't have arrows at that point -.-
defeat the wizrobe in the snowhead temple. use bunnyhood to defeat him easier.

In the Fire Temple (4th temple). The Bow of Light can be found in the Sand Temple (5th temple)
