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:

No any data from "truss -p" or ktrace.
kill -9 or any other kill is not affected.
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).
In this state, procstat show:

Just CC to freebsd-current@ , because not sure that this problem of
freebsd-gecko@ only.
Anyone else met with such behavior ?
