Terri Calvesbert, now 19, suffered 85% burns as a toddler at her Ipswich home in 1998.
Recent pictures of her posted on social media prompted online abuse, and were shared thousands of times.
Terri, who said she is "strong enough" to cope, has launched an online anti-bullying page, and is petitioning the government to take action.
Now living in Sudbury, she said was "really angry" at a Facebook post which asked people to "like and share" if they were "not ashamed" of a picture of her.
The post has been reported to the social media site.
However the teenager insisted living with such serious burns has equipped her with the strength to cope with online trolls.
Terri, whose story was first reported in the Ipswich Star, said: "I can't pretend for a single moment that it's been easy for me growing up, but I'm a stronger person as a result.
"I'm not going to let it get me down, but I do want it to stop."
Terri and and two friends, Michelle Wright and Gavin Jaques have set up a Facebook site called the Campaign to stop cyber bullying.
They will urge the government to get Facebook to take down offensive posts, delete accounts and track offenders down.
Her friend, Michelle Wright, said: "Most people would be appalled that trolls could pick on her. I just knew a lot of people would have got behind it. Terri is so brave."
MP James Cartlidge has taken up the case and has written to home secretary Amber Rudd to bring it to her attention.
Facebook said attacks of this kind would not be tolerated and that the offensive content had been removed.

Enrique is leaving after three years in charge at the Nou Camp.
Ibai Gomez hit the post for Alaves before Messi scored his 54th goal of the season with a 20-yard curler.
Theo Hernandez bent in a free-kick to equalise, but Neymar turned in from close range and then Messi played in Paco Alcacer right on half-time.
It has been a disappointing season for Barcelona, who finished runners-up to Real Madrid in La Liga and were eliminated from the Champions League by Juventus in the quarter-finals.
They did at least restore some pride with victory over last season's second division champions in what was the final match to be played at Atletico Madrid's Vicente Calderon Stadium.
There were some records set along the way as Enrique's team retained the trophy, having beaten Athletic Bilbao and Sevilla in the last two finals.
Messi, who struck the opener after exchanging passes with Neymar outside the penalty area, became the first player to score in four Copa finals since Athletic Bilbao's Telmo Zarra in 1950.
Neymar, who forced in Barcelona's second when Messi played in Andre Gomes to cross low from the right, is the first man to score in three successive Copa finals since Ferenc Puskas, who achieved the feat with Real Madrid between 1960 and 1962.
Messi's through pass for the third goal was sublime, and was finished calmly by Alcacer - who has been inconsistent since his move from Valencia last summer.
The one major worry for Barcelona was a nasty head injury to Javier Mascherano, who was carried off on a stretcher after an early collision with Marcos Llorente,
He suffered concussion as well as a cut to his head, and an injury to his right knee that will need further tests, the club said afterwards.
