Make sure you have r247156. It's an i386 regression in clang 3.2 fixed
promptly after update on /stable/9. With development branches only their
tip is supported e.g., not the period between 2013-01-14 and 2013-02-22.

To fix the crash either:
- build firefox with another compiler (gcc46, gcc47)
- update base and rebuild firefox
- apply only the clang fix[1] and rebuild firefox

[1] $ cd /usr/src
    $ svn di -c247156 svn://svn.freebsd.org/base | patch -p2
    $ make -C lib/clang
    $ make all install -C usr.bin/clang/clang
