Hi, two things comes in mind:

1) You can use directly (xlib:window-id window) to know the window id.
But I think it can change each time you reboot.

2) If you always want a different frame for each firefox window, you can
setup a default frame which absorb the first firefox window and then
create a new one for each others.
This can be done with a permanent new window hook (need to be written).

Have a look at clfswm-nw-hooks.lisp. Indeed, you can ask if you want
more details or I can write the code if needed.
And, please, share your results here.
