Firefox 3 smart bar is just too smart 18 years ago
the super-wicked bar is a respectable addition. it works like just the all-hyped instant search technology (e.g. of google, copernic, etc.) by (instantly) finding any url (which includes descriptions) containing the relevant search phrase. it's super-wicked. and the greatest part is that it learns!
i could see why someone might want to disable it, but i find it supremely useful. i don't have to search through my history...the super-wicked bar does it automatically for it. it's like my whole history is instant-searchable in the url ("super-wicked") bar!
more and more software is continually making use of instant search technology (e.g. application launchers like Launchy), and it's a great thing indeed.
