You can discover and figure out the different windows without needing
openbox to do it.
This is especially relevant to the web browsers, which as Gary pointed out
do not differentiate themselves on start up.

How I handle such applications is to use a start up script  (in my case
part of the ".xinitrc" but can be any client start up script, or direct
command call).

For this I have a 'wait for window' script  "xwin_find"
This essentially a loop that looks for a specific window using "xwininfo"

With it I can then do things like...

  google-chrome &
  if id=`xwin_find 60 "Anthony.* - Google Chrome"`; then
    echo "Chrome Window Found (id=$id)"
    sleep 1  # pause a moment
    xwit -iconify -id $id
    echo "ERROR: Chrome Window NOT FOUND\!"

This will wait (up to a full minute) for the specified window to appear (
and load the appropriate startup page to identify it), then minimize
(iconify) the window,  but you can also resize, position, or move to a
specific window manager desktop, using the appropriate tools.

It works with chrome, firefox, or other tools too.

Alternatively, if you don't mind not having a timeout, you can use "wmctrl"

   while :; do
     wmctrl -l | grep -q "$string" || continue
     : do what you need

Or even "xdotool" using its "search -sync" function

   firefox &
     xdotool search --sync --onlyvisible --class Firefox \
             windowsize %@ 900 900 windowminimize %@

I hope this helps.
