cannot set the button order, of yes please tell me how to do to install the close, monimize and restore and set the order

The button is meaningless, it is on any window. We really need an addon that, instead of closing the window, firefox throws it down (minimizes), so that the "close" button works just like "minimize". Old addons (Minimize to tray and "minimize when close, close tab (s) on Esc (Delete)") do not work! Please make such an addon.
