I haven't had the particular need to print from  firefox on NetBSD
recently; after reading this I tried...

The moment I hit the 'Print'  menu item to get the dialog, my firefox
process goes in an endless loop, becoming completely unresponsive; the
trace is as follows (just an excerpt; it repeats ad inf.):

69     20 firefox  __clock_gettime50(0x3, 0x7c8abf31dc30) = 0
  2669      1 firefox  poll                        = 0
  2669     20 firefox  ___lwp_park60               Err#60 ETIMEDOUT
  2669     20 firefox  __clock_gettime50(0x3, 0x7c8abf31dc50) = 0
  2669     20 firefox  __clock_gettime50(0x3, 0x7c8abf31dc90) = 0

669     20 firefox  __clock_gettime50(0x3, 0x7c8abf31dc30) = 0
  2669      1 firefox  poll                        = 0
  2669      1 firefox  __socket30(0x2, 0x1, 0)     = 36
  2669      1 firefox  setsockopt(0x24, 0xffff, 0x4, 0x7f7fff480edc, 0x4) = 0
  2669      1 firefox  setsockopt(0x24, 0xffff, 0x200, 0x7f7fff480edc, 0x4) = 0
  2669      1 firefox  setsockopt(0x24, 0xffff, 0x800, 0x7f7fff480edc, 0x4) = 0
  2669      1 firefox  setsockopt(0x24, 0x6, 0x1, 0x7f7fff480edc, 0x4) = 0
  2669      1 firefox  fcntl(0x24, 0x2, 0x1)       = 0
  2669      1 firefox  fcntl(0x24, 0x3, 0)         = 16777218
  2669      1 firefox  fcntl(0x24, 0x4, 0x1000006) = 0
  2669      1 firefox  connect(0x24, 0x7c8ac39aa9c8, 0x10) Err#36 EINPROGRESS
  2669      1 firefox  fcntl(0x24, 0x4, 0x1000002) = 0
  2669     20 firefox  ___lwp_park60               Err#60 ETIMEDOUT
  2669     20 firefox  __clock_gettime50(0x3, 0x7c8abf31dc50) = 0

...

So no printing from firefox for me at all. This is 9.99.31 from today
(amd64), firefox 71.0.
