Package: iceweasel Version: 2.0+dfsg-1 Right-click on the navigation toolbar, and choose "Customize...". Drag the location bar into the bin of toolbar items. Drag it back onto the toolbar in the same place. Click "Done" in the customize window. The menu bar no longer works.- Josh Triplett
Im having the same issues , where if if I try to customize the toolbars the very top menubar stops responding to mouse clicks.
