FWIW: Today I built firefox-gtk2 on my AMD64 (something
like 2.99.10 kernel, with a 2.99.9 or 2.0H userland).

Trying to invoke it, by

  firefox-gtk2 http://www.NetBSD.org/

...dumps core everytime.  If I click the mouse immediately as
soon as twm gives me the frame for positioning the initial
window, no graphics are produced.

If I hold off for a half second or so before positioning the
initial window, I get a smallish window (at http://www.netbsd.org/,
so it has done a little bit of network activity), but still dumps
core before I see anything but blank page with some firefox toolbar
widgetry.


Just a datapoint, since someone said that firefox-gtk2 was working
for them.

Links still works very nicely.  (^&
