One reviewer mentioned that you cannot use foil in this toaster oven. (See 1-star reviews). I looked at the owner's manual for this product on Frigidaire's website. Here is the only restriction regarding aluminum foil I could find.

16. Do not cover Crumb Tray or any part of the Oven
with metal foil. This may cause overheating of the
Oven.
