I'm not sure of what may be causing this firefox error, but someone else 
should be able to chime in.  Until they do, you could first check dmesg to 
make sure you're not running out of memory, then you could update your 
@system, before you try again to emerge firefox like so: 

MAKEOPTS="-j1" emerge -uaNDv --with-bdeps=y firefox
