Attachment: screenshot 1 - Modal save dialog doesn't respect standard Windows7 mechanism 'Automatically move the pointer to the default button in a dialog box' (SnapToDefaultButton).png

STR:   (Win7_64, Nightly 44, 32bit, ID 20151012030612, new profile, tested on DPI=125%)
1. Switch firefox window to maximized mode
2. Press Ctrl+S on this page   [the dialog will appear]
3. Dock the modal window to the right side of screen
  (or at least (A) move the modal window so that its upper right corner was at 
                   some distance from the firefox window's upper right corner
            OR (B) Resize modal dialog so that "Save" button was at some distance
                   from the place where pointer appeared after Step 2.)
4. Press Escape   [modal window will close]
5. Press Ctrl+S

Result:    The modal window appears on the place defined by user in Step 3, BUT
           pointer isn't placed directly above "Save" button.

          (Looks like Windows has some kind of "default window's size and placement". When the
           window appears, pointer moves to the "Save" button first, and only then the modal window
           resizes and moves to user-defined position. But the pointer stays at its initial position)

Expectations: The pointer should be placed directly above "Save" button.

This is VERY long-standing and annoying bug. GoogleChrome doesn't expose this issue.

Correction:
Now I tested this better, and it appears to be reproducible on Chrome 49, Firefox 51 and AIMP 3
So this can easily be an unsolvable Windows 7 problem  (I don't know if it's fixable on Firefox side)
