wine_firefox_with_menu_bar

With firefox esr (v 38.8 as a portableapp) if the menu bar (File, edition...)
is not displayed, part of the tabs is hidden by my window manager (kwin under
kde).
There are 2 cases : when window is maximized, then part of the tab is hidden,
when the window is "restored" then display is acceptable

If I enable the menu bar (menu view/toolbars/menu bar, I get there by doing
ALT+F, and then navigate with keyboard and mouse), then the menu bar is not
visible.
