Autocompletion Rated 4 out of 5 stars
This Add-on is great, should be integrated in firefox.
Very efficient to switch search engines.
However, It would be great to be abble to desactivate the autocompletion while typing in the bar.
It often make my search wrong cause I'm not use to put a space after typing my word.
Thanks a lot
You could set browser.urlbar.autoFill property to false in about:config.
