Here is a list of a few useful little plugins/apps that will power-up your Safari browsing experience:
-Tabexpose 1.7.1 (hit F8 and see all open tabs exposed on your desktop)
-Saft 9.0.2 (type ahead – keyboard navigating and full screen browsing in Safari – let go of your mouse/trackpad)
-Inquisitor 3.0.3 (view google hits as you are typing in the search box)
-Speed Download 4 (this thing actually makes downloading 2, 3, even many times faster – see files normally downloaded at 500kb/s being poured onto your hard disk at 3Mb/s)
