No menu bar in libreoffice/firefox

Hi @Holgerrpl,

maybe you can shed some llight on this thread about HUD please?:

HUD not working

HUD (heads-up display) sounds interesting, but I can’t get it to work. (Ubuntu MATE 16.10 Alpha 2) I’ve checked Enable HUD in MATE Tweak and rebooted, but CTRL+ALT+Space does nothing. I have tried all combinations of left and right ALT and left and right CTRL keys. Are there some unmentioned prerequisites for this feature? I notice that there’s no HUD shortcut listed in Keyboard shortcuts. Should I add it? What is the command for HUD?
