In most circumstances with a FIRE on final approach it is wise to continue to land, declare emergency if you can, stop on runway and complete checklist actions/handle situation as appropriate. However, the exact point where you changeover from completing the airborne checklist to concentrating on the landing first is down to Airmanship/complexity of the aircraft/circumstances. This is another situation you can best consider as a development of your skills. Cheers
