I've been having lots of Firefox crashes.  I am running Firefox from
ports (v 39.0.3) on amd64 5.8 -stable.

I increased my limits in login.conf.  I have tried a few different
combinations, but this is what I'm doing currently:

$ getcap -f /etc/login.conf staff
staff:datasize-cur=3500M:datasize-max=infinity:maxproc-max=512:maxproc-cur=256:ignorenologin:requirehome@:path=/usr/bin
/bin /usr/sbin /sbin /usr/X11R6/bin /usr/local/bin
/usr/local/sbin:umask=022:datasize-max=512M:datasize-cur=512M:maxproc-max=256:maxproc-cur=128:openfiles-cur=2048:stacksize-cur=4M:localcipher=blowfish,8:ypcipher=old:auth=passwd,skey:auth-ftp=passwd:

My computer has 12 GB of physical RAM, so I don't figure I need to be
terribly conservative with datasize rates.  Meanwhile, I've been
monitoring 'top' and this is pretty typical for Firefox:

  PID USERNAME PRI NICE  SIZE   RES STATE     WAIT  TIME    CPU COMMAND
 3188 danboyd   30    0  666M  689M onproc    -     3:41 16.46% firefox

I don't have a super high number of tabs open either.  I had a bunch
open this morning, but I closed most of them in an attempt to ward of
the crashes.  I have had 7 or 8 crashes in the last hour...  Among the
tabs open, I do have two pinned tabs running gmail (work email,
personal email), and I assume those are relatively resource intensive.

Another odd thing is that I've noticed that Firefox virtually never
crashes when it's the active window.  It always seems to be in the
background.  Anyway, any help would be much appreciated.  I have a
core dump if that would be of any use...
