I will try that soon. I didn't mean "there is a bug in firefox"; I meant that in my setup, running/using firefox (leaving it open and not visiting the virtual desktop does not increase wired) is what makes the difference. You have found a vastly smaller/simpler reproducer, and that's huge progress.
