I'm still using xwd(1) to grab a window (using -frame to add
the decoration of the window manager) here, and convert it
then to .png with the Gimp. Of course, I take care of displaying
just the interesting part of the web page that I need by scrolling
to the interesting part.

If you need a complete snapshot of the page, you may try this:
open Firefox with some insane big -geometry settings, perhaps
to a big virtual screen in X; and then grab that whole window
with xwd(1). I didn't try that, but it may be enough. If your X server
won't handle this big a screen, try with a nesting server like
x11-servers/xorg-nestserver.

Good luck!
