I have a crack in the front mortar. I properly did the 6 days of slow firing. This is my second full fire to make pizzas. Can I fix this?
Super Easy (and inexpensive) Fix!
When the oven is warm, simply squeeze some High-Temperature Mortar into the crack.
In about 3 minutes it will be hard… then in 2 hours, it will be rock-hard and resistant to future cracking.

I finished my third curing fire and noticed this hairline crack. Its to small to apply mortar and not deep. Any advice?
This one I wouldn’t worry about, at least for now.
It doesn’t appear to reach the edge of another joint. Compare your photo with the one up thread, and you’ll see that’s a crack that goes through more than one course, and from the chimney.
If it gets deeper/longer/wider, then @BrickWood’s advice would apply.
