I like toolbars for quick, frequent-but-not-that-much actions, like exporting to a pdf in LibreOffice.

But I also like menu bars, as those give you some shortcuts if you often use a functionality. As an example, and since I type this into Firefox right now, after glancing at the menus, Alt+V,Y,N disables the page stylesheets, Alt+T,S synchronizes the account, etc.

like menubars, the toolbars give you the short cuts when you hover over them.
