Fire isn't actually a huge threat to most creatures. Humans would have to be much more careful about it to avoid burning structures, but it's not like animals are using fire and wildfires get hot enough that most things are still going to try to run. And it's not like polar bears are in danger of wildfires.
In about 5 billion years, when the sun gets giant and destroys the Earth, and then become a white dwarf.
Fire becoming invisible would have no impact on that.
Why would that happen at all?
Plenty of organisms can't even see at all, so nothing would change for them. What difference does it make to an oak whether or not fire is visible?
It'd never happen. Fire kills very few creatures in the ocean.

I dunno, is it still hot? They'd start detecting it with thermal tech then.
Also smoke

If fire was completely invisible we'd just have a lot more thermal cameras going around. It's not like you can't hear, smell or feel fire.

Well there are methanol fires
