Those tools work by using an inherent X11 security hole by reading out the root window, it's not relevant to framebuffer in the kernel sense. Note that you can't use a global shortcut key in X11 while a typical right click context menu is open, because these take a X11 grab and even screen lock can't activate.. Then only the delay approach will work (if desired then together with a shortcut if the shortcut key is hit before opening the context menu). Fortunately in this case you only wanted a dropdown in firefox, which isn't implemented like that. This popup menu problem is solved with Wayland (most importantly the not screenlocking aspect of it), but so is the root window security hole, so the compositor/WM needs to take the screenshot and tools like import/scrot won't work.
