It's not borken.  Your ports are probably just out-of-date and were
built against a previous version of libc (libc.so.6) which doesn't
have thr_getscheduler.  What does `ldd /path/to/firefox_binary`
show?

I don't think rebuilding just firefox is going to fix the problem
since it depends on other libraries that depend on libc.so.6,
not libc.so.7.

What does 'readelf -sW /lib/libc.so.7 | grep thr_get' show?  Is
firefox linked against libc.so.7 or libc.so.6 on your system?
