Febreze will freeze but once it warms up the Febreze will return to normal and be just fine.
I've had Febreze air freshener spray freeze before but once brought into a warm house it thawed out and was just fine.
Spray paint cans, air fresheners and aerosol spray cleaners can freeze but normally they are fine once thawed out and brought back to room temperature.
It's best though to not leave Febereze or air fresheners or other aerosol spray cans or spray paint out in the freezing temperatures.
Always try to keep the spray cans including air fresheners inside at room temperature or at least above freezing.
