I am suffering from the same problem. Today again, when I logged out from the computer, it told me about the hanging firefox-bin process, but I just logged out anyway.
This left two processes bumming around. 18727 ? Sl 0:25 /usr/lib/firefox-3.6.24/firefox-bin 18768 ? Tl 0:04 /usr/lib/firefox-3.6.24/plugin-container /usr/lib/adobe-flashplugin/libflashplayer.so 18727 plugin true I have tried to strace -p 18768, but with no success, even as root: root@quad:~# strace -p 18768 attach: ptrace(PTRACE_ATTACH, ...): Operation not permitted I also tried to send SIGCONT ( kill -18 ) to 18768, but with no success. It seems that the firefox-bin process is waiting for the plugin- container, which is a stopped process, thus waiting forever. michael@quad:~$ strace -p 18727 Process 18727 attached - interrupt to quit futex(0xa2cffbd8, FUTEX_WAIT, 18767, NULL When exiting firefox there should be a timeout waiting for plugins and if the plugin-container or any other spawned process is detected in a stopped state, it should be just killed with SIGKILL. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/764621 Title: /usr/lib/firefox-4.0/plugin-container hangs upon Firefox exit, which prevents computer shutdown from GNOME Status in “firefox” package in Ubuntu: Confirmed Bug description: Binary package hint: firefox Every time I exit Firefox before rebooting this host running a classic GNOME session, it hangs there, effectivel preventing the reboot from taking place unless Firefox is first force-killed. The cause seems to be that Firefox's plugin container has a dozen of Gnash sub-processes that won't terminate.
