Can it be used on a firebox

It depends on what type of firebox you are talking about. for a smoker or grill it worked fine. Other applications I don't know.

Can I use this to reattach a glass door on a convection oven? The door fits into a channel which has hinges on it to swing the door open.

Hi, Thank you for your inquiry. Being we have not tested this product for this application we can not say if this would work for you or not.

Could this be used to fill in small gaps between my fire box and smoke chamber, to stop any unwanted air flow?

Yes. Thats what I used it for. It worked great.

Is this flexible after it dries?

It remains flexible. They actually state on product tube, "25% Movement Capability".
