She was taken to Jersey City Medical Center, where she was pronounced dead a short time later.
It's not yet clear what sparked the fire, which broke out around 5 a.m. But investigators say there were lots of papers and other clutter inside the home that apparently helped fuel the blaze.
Details on the injuries sustained by the firefighters were not disclosed, but none were considered serious.
Authorities also briefly evacuated three nearby homes that were slightly damaged by the fire, but no other injuries were reported.
