Firefox search box

I'm not sure why but I have this mental barrier of using the Firefox search box. If I wish to go to a site I'll either use the address bar which uses Google's Lucky Search or I'll manually type in google.com and then type in my query.

Firefox 2.0 when it is finally released is going to have a Google Suggest style AJAX search box that will autosuggest the search query. However, I dont think this is enough. I want something like a top 3 results automatically show up for a search query I put in without having to go to the Google.com site. This module does something similar which I'm sure can be hacked up to be used with the Firefox search bar/box.
