Comment 24 for bug 907721

Why should it matter if it's obscuring the search field? You usually have to put the mouse in the search field to begin typing, and that makes the message go translucent, allowing you to see the field. Besides, where it is now has a greater chance of covering content than the toolbar, and the content is what's most interesting.

A close button might also solve that problem, but that's a different conversation altogether.
