In modern Windows 10, you still get that in well-designed applications. In poorly-designed applications (hate to throw shade at Firefox, but it is one), you may be able to still get that menu by hitting ALT+SPACE. It just pops out of nowhere because there's nowhere to click to get to it.

ALT+SPACE, M, arrow keys is forever in my brain due to so many poorly behaved programs which would open their window somewhere off-screen, and that was the way to move them back onto the screen.
