OSFile implementation loads libc.so.6 if it is available! That is, if
you have the compat6x package installed, it loads
/usr/local/lib/libc.so.6, even while /lib/libc.so.7 is already loaded.
This wreaks havoc when it later tries to call libc functions via libffi,
and the result is that it calls into a completely bogus PLT entry. Most
of the time, this leads to a crash.
So the easiest way to avoid the crash for now is to uninstall the
compat6x package, and making sure there is no libc.so.6 in
/usr/local/lib/compat. Then Firefox should start with no problems.
As a better fix, please try dropping the attached file into the
/usr/ports/www/firefox/files directory, then rebuild the firefox port
from scratch, and reinstall it.
