Make your Firefox looks like Google Chrome.

Chrome theme: 

That's what I usually use to make my firefox looks better and eat less space on a screen:

• Chromifox Extreme theme
• Chromifox Companion
• Tabs on top
• Source Viewer Tab
• Personal Menu
• Hide Menubar
• All-in-one Sidebar
• App Tabs - pin tabs
• Download Statusbar
• Menu editor - I make "Open in a new tab" the first item in the context menu

Google - поиск по умолчанию в адресной строке:
Search with Google directly from your address bar:

• вводим в адресную строку / input address about:config
• ищем параметр / search parameter keyword.URL
• изменяем на / change to http://www.google.ru/search?ie=utf-8&oe=utf-8&aq=t&client=firefox&q=
