I have often had firefox hang like that. This was firefox-220.127.116.11
from pkgsrc, running on an i386 laptop with NetBSD-4.99.20, compiled
on the same laptop with a somewhat older version of -current (probably
4.99.16). According to "ps -s", almost all lwps were "parked", but one
was waiting for something else (a socket, I think). Locking the screen
(via xlockmore) and/or suspending the laptop seemed to have something to
do with triggering the bad state, but I didn't do any scientific tests
to verify that hypothesis.
I recompiled firefox and almost all its dependencies on the same version
of -current that I am running, and haven't seen the problem again.
This makes me suspect a binary compatibility issue between 4.99.16 and
