I have recently seen examples In modern media (won't lie, a lot of it has been in TW games) of the use of fire arrows in ancient warfare, and i am skeptical that in actual history they were used very frequently. Were fire arrows used at all in warfare to useful effect, or are they more of an added dramatic and aesthetic feature of modern media? (This is my first post here so i hope i don't break to many rules)
They definitely were A Thing, though as you'd expect, not nearly to the extent media these days would portray. I commend to your attention this thread, linking to previous answers by u/GBFel and u/Freevolous, and some extra questions answered by u/GBFel in the thread linked.
