I tried doing an strace (strace -p 32499) on the firefox process, here are the last few lines before it hanged.

It seems like firefox (PID 32499) is waiting on process 32679. Unfortunately, I cannot find more information about process 32679. It's not in the Processes tab of System Monitor. When I tried to kill 32679, it also kills the firefox process with the following entry in the strace.

| futex(0xb323ebd8, FUTEX_WAIT, 32679, NULL) = -1 EINTR (Interrupted system call)
| +++ killed by SIGTERM +++
| Process 32499 detached

Hope this helps. This is easily reproducable.
