>Description:
Two days ago I removed firefox and reinstalled it. This was done with my /etc/mk.conf file which includes these lines:
PKG_DEFAULT_OPTIONS+=pam ssl -cups -pulseaudio -alsa
PKG_OPTIONS.firefox+=oss  debug
.if "${PKGPATH}" == "www/firefox"
  CFLAGS+=      -ggdb
  CXXFLAGS+=    -ggdb
  INSTALL_UNSTRIPPED=   yes
.endif

I rebuilt my OS yesterday with "MKDEBUG=yes" and "MKDEBUG_LIB=yes" and
installed the resulting "debug.tgz" and "xdebug.tgz" sets.

I then started firefox 50.1.0 in a terminal emulator.  Here is the output:

====I have other backtraces that are identical.=====

>How-To-Repeat:
When I leave firefox 50.1 running, started either from a terminal or from the gui, the crash will eventually recur.
It seems to happen more often when I have several firefox windows open. Sorry I can't be more specific.
>Fix:
Not known to me.
