Would it be possible to create a script to save the desktop and screen position for each firefox window on close and restore them to the recorded desktops and positions on open? I haven't used i3 much (or arch at all), but I'm fairly certain I did something similar using Xubuntu some years back.

I did that on xubuntu too. Used xdotool, wmctrl and something else I can't recall.

I'm vaguely aware of tools that'll do it for i3 but thus far I've just avoided restarting as much as I can. The call-out to James Mickens is not altogether inaccurate (:
