To disable the menu bar in konqueror , you have a specific action in menus. If you want to do this by hand, just add the following directive in your ~/.kde/share/config/konquerorrc file:

[KonqMainWindow]
MenuBar=Disabled

This tip is interesting because you can also apply it for any KDE application that doesn’t support this feature.

For example, in kmail , you can add the “ MenuBar=Disabled ” statement in “ [Main Window] ” section: this will have the same effect as in konqueror.
