I'm no chemist, but that does not seem plausible. Fire needs three things: fuel, oxidizer (e.g. oxygen), and heat. [1]
No matter how much oxygen, the atmosphere would not ignite without fuel.
Forest fires would get epic though.

This trivia about Nitrogen used to be my favorite when I was studying chemistry in the school. Like there’s lot of nitrogen in the atmosphere and oxygen but they don’t “burn” because (almost all?) nitrogen oxidation is endothermic!
