In 1972, while still playing for CSKA Moscow, Firsov began working as an assistant coach for the club.
Between 1976 and 77 he was the head coach of the Soviet junior team, which won a bronze medal at the 1977 World Championship.
In 1989, Firsov was elected to the Congress of People's Deputies, running on a policy of improving health conditions and sporting facilities.
When Firsov was only one month old, his father was killed in action during World War II and thus, he was raised by a single mother.
Instead, he played bandy which was more popular than ice hockey at the time in the Soviet Union.
During the summer, Firsov would play football which helped keep him in shape all year long.
Due to the lack of money in the family, Firsov had to make his own stick and skates.
