>Description:

When I start firefox-59.0.1, in two out of three tries it behaves as if
there would be no network connectivity. This does not depend on name 
resolution, it also can not connect to http://$numerical_ip urls.

Closing firefox and restarting (a few times untill it works) is a
woraround.

When it is not working, there is only a single firefox process, while in the
working case, always multiple exists (a new process for each open site, I
gues, plus a few "administrative" and GUI ones).

>How-To-Repeat:

Not sure. Ktrace shows things like:

   555      1 firefox  CALL  recvmsg(4,0x7f7fffffda80,0)
   555      1 firefox  MISC  msghdr: [name=0x0, namelen=0, iov=0x7f7fffffda70, iovlen=1, control=0x7f7fffffdab0, controllen=80, flags=4000000]
   555      1 firefox  RET   recvmsg -1 errno 35 Resource temporarily unavailable

but I am not sure this is related. Maybe something in libpthread
or firefox needs to be adjusted for the recent socket changes?
