I have to correct myself:

NetBSD 5.1.2 has the same problem, as long as a kernel without
  options FULL
or
  options DIAGNOSTIC
or
  options LOCKDEBUG
is used. My kernel had "options FULL", which is known to fix issue PR
#44387. And a 5.2 kernel with FULL works too.

What we see is the infamous pthread-mutex bug, which leaves a thread in
"parked" state forever.

Everybody who has the same problem: please put "options FULL" into your
kernel config file and make a new kernel. It will fix these problems with
Firefox (and other programs).

We still have to fix #44387, though...
