Which address bar position is best?
1: Address bar, menu, toolbar, tabs
2: Menu, address bar, toolbar, tabs
3: Menu, toolbar, address bar, tabs
4: Menu, toolbar, tabs, address bar
It's interesting that the major browsers use very different layouts. Internet Explorer 7 and 8 both use layout 1, while Firefox and IE6 are closest to layout 3 (ignoring the lack of built-in tabs in IE6). Opera uses layout 4, while Chrome doesn't really fit into any of these (though it's most like 4).
