i like YubNub a lot, probably because i m a big fan of using the keyboard rather than the mouse ;-)
YubNub

here is how i use it with Firefox ( I love Firefox :-* :-* )

1) open a new tab in firefox ( Ctrl-Tab )
2) type in ``about:config" ( without the quotes ;-) )
3) then in the ``filter" field type in ``keyword.url" ( without the quotes ;-) )
4) my firefox spat out the following

5) in the window below the ``filter" field double clink on the highlighted field
and in the popup window write the following:
