Absolutely pontifex.
If the fire indication is not accompanied by a complete loss of power, get yourself cleaned up and accelerated first.
The other good thing about a fire (if the aircraft systems and checklists are well designed) is you can completely shut it down and feather by simply pulling the illuminated handle, rather than messing about with power and/or prop levers. A lot less chance of getting the wrong one. Certification should be updated to require ONLY pulling a flashing fire handle and nothing else.
