I think you were looking for windowinfos.lua in wrong directory.
It is not saved into .ion3/ itself, but in .ion3/default-session-0/
(if you did not changed your ion session directory).

Here I think that instance should be lowercase, but I'm not sure.
First try to omit instance.
Also the script may not work in specific circumstances. I have two
computers, but only on one is the solution working reliably. (The
other computer is old, some plugins in iceweasel installed etc.)
