Hi, On recent FreeBSD version (tested on two host: one from svn://svn.freebsd.org/base/head ( r310507 now) and second from https://github.com/FreeBSDDesktop/freebsd-base-graphics.git / drm-next-4.7 ) and latest firefox ( firefox-50.1.0_4,1 ) I often get into a situation where firefox is hands. It looks like unresponsive window: https://snag.gy/gKPhnb.jpg with follow information from procstat: --- % procstat -t 18827 PID TID COMM TDNAME CPU PRI STATE WCHAN 18827 100754 firefox - -1 152 sleep uwait 18827 101508 firefox Gecko_IOThread -1 130 sleep kqread 18827 101509 firefox Socket Thread -1 128 sleep select 18827 101510 firefox JS Watchdog -1 121 sleep uwait 18827 101511 firefox JS Helper -1 120 sleep uwait 18827 101512 firefox JS Helper -1 120 sleep uwait 18827 101513 firefox JS Helper -1 120 sleep uwait 18827 101514 firefox JS Helper -1 120 sleep uwait 18827 101515 firefox JS Helper -1 120 sleep uwait 18827 101516 firefox JS Helper -1 120 sleep uwait 18827 101517 firefox JS Helper -1 120 sleep uwait 18827 101518 firefox JS Helper -1 120 sleep uwait 18827 101519 firefox JS Helper -1 120 sleep uwait 18827 101520 firefox JS Helper -1 120 sleep uwait 18827 101521 firefox JS Helper -1 120 sleep uwait 18827 101522 firefox JS Helper -1 120 sleep uwait 18827 101523 firefox Hang Monitor -1 132 sleep uwait 18827 101524 firefox BgHangManager -1 125 sleep uwait 18827 101525 firefox -

If i apply 'xkill' on stale firefox windows it come to 'stopped' process in 'top'. And also there is no reaction on kill (e.g. -19, SIGCONT).
