Hello! I don't see a toolbar in that screenshot. If you mean the panels, you can pull them to reveal their contents, or go reset your workspace, in Window > Workspace >Reset Workspace, as suggested.
I am with Pierre here, in that I do not see, from your screen-cap, what is missing, or what has changed for you.
If the suggestion to Reset Workspace, or trashing your Prefs, does not fix things, please post another screen-cap, showing exactly what is missing, or what has changed.
