Rearranging the Google Bar
firefox;google;css
If you have Firebug installed you can view the id's of the element by right-clicking on the item and selecting Inspect Element with Firebug. The Google bar seems to be an unordered list with class gbt for the elements. To apply custom css you could use a tool like stylish although you might want to use Javascript for more control using something like Greasemonkey.
