Police arrived just after 10 p.m. to find flames engulfing the more-than 75-year-old, 2,450-square-foot Lester Street home at the corner of Halstead Avenue.
Both the homeowner and the firefighter were taken to Hackensack University Medical Center along with the seriously injured homeowner, responders said.
More than $1,200 had been raised for the family on a GoFundMe as of Wednesday morning.
Authorities were investigating the cause of the three-alarm blaze.
Firefighters from Carlstadt, Hasbrouck Heights, East Rutherford, Lodi, Passaic, Rutherford and Wood-Ridge were among those who assisted their borough colleagues.
