I tried doing an strace (strace -p 32499) on the firefox process, here are the last few lines before it hanged.
| shmdt(0xa8fe1000) = 0 | shmctl(1075937401, IPC_64|IPC_STAT, 0xbfa56e0c) = 0 | shmctl(1075937401, IPC_64|IPC_RMID, 0) = 0 | shmdt(0xa9013000) = 0 | shmctl(1075904621, IPC_64|IPC_STAT, 0xbfa56e0c) = 0 | shmctl(1075904621, IPC_64|IPC_RMID, 0) = 0 | semctl(12779521, 0, IPC_64|IPC_RMID, 0xbfa56e58) = 0 | close(95) = 0 | futex(0xaac0bcec, FUTEX_WAKE, 1) = 0 | futex(0xb323ebd8, FUTEX_WAIT, 32679, NULL 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.
