Why waste vertical space with
proprietary toolbars when you only use one or two functions? Just drag and drop the (Google) toolbar icon(s) you want on to your navigation bar. Then hide your (Google/Yahoo/etc) toolbar.
I like the
Google Pagerank and
Google Autofill functions but I don't need the rest of the Google toolbar. So, I just right-click on a toolbar and then click on Customize and move the corresponding icons to my
Navigation toolbar as seen below.
