Hi Masayuki, Our test harnesses accomplish this by piping the output of Firefox through one of the stack fixing scripts in tools/rb[1]. fix_linux_stack.py uses addr2line, which should at least give you function symbols on Nightly. You could use my GDB symbol server script[2] to fetch the actual debug symbols from the symbol server if you want full source line information.
