it was totally fresh firefox install w/no existing config nor plugins/addons
w/e they are on that browser, figured i would uninstall once i found it
suffering from mmap: mandatory W^X too, however i believe it was
running/idling with these tabs:
https://github.com
http://ftp.openbsd.org/
https://www.google.com/
http://www.openbsd.org/faq/ 
http://cvsweb.openbsd.org/cgi-bin/cvsweb/

can still provide exact urls off-list if you want, as it still seemed to
launch with same set of tabs i left it running with while i was testing it
before reboot to get rid of the msg.

fwiw. chrome seems to average around 3 messages per tab on launch, so what
i got was a flood of +350messages just to get the browser running steady.o
in comparison the firefox is almost silent.
