lol, all the tools in the world do not sometimes replace it with a game.
I managed to get the desired results by changing the font size in the search text box from 25px to 24px. In both Firefox and Chrome, I thought it was good.
I was able to do this using firebug for firefox and the built-in developer tools for chrome.
Learn to use them, because they are very important for such settings.
Good luck.
EDIT a more detailed example of what I changed
li.search input[type="text"] { border: 0; -webkit-border-radius: 0; -moz-border-radius: 0; border-radius: 0; background: #ebebeb; margin-left: 20px; position: relative; top: -1px; width: 205px; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box; font-family: 'waukegan'; font-size: 24px; padding-top: 2px; padding-bottom: 3px; padding-left: 8px; }
