Solução:

1)Necessário atualizar a versão do libstdc++6, assim:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9
sudo apt-get upgrade libstdc++6

2)Checando, pelo menos a GLIBCXX_3.4.22' deve estar instalada:
comando ====> strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX


root@brainiac-desktop:/usr/lib/firefox# strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX
