Firefox crashes in the default Debian build

[r59vde]

for me, on the default debian/mate image, fully updated (both mrfixit update script and apt), firefox crashes immediately on startup, does not matter network state
crashes when connected to wired network or wireless, no matter how started
from terminal :

rock@Debian-Desktop:~$ firefox
