Firefox (tulikettu or tulirepo or tulikko) is a mythical creature in the folklore of northern and eastern Finland.
[1] According to folk stories, the Firefox lives far away in hideouts in the woods, or in the north, and very few are said to have seen it.
[2] According to stories, the leather of a Firefox has been used to illuminate powder storages at nights instead of dangerous open fire.
[2] Firefox has given its name for northern lights which are called "fox fires" (revontulet)[4] in Finnish language.
In Lapland it has been told that the Firefox causes the northern lights with its tail which flings sparks when it touches low hanging branches or bushes while the fox is running.
