great addon Rated 4 out of 5 stars
I love this. One thing I am not used to with FF is the auto-fill functionality. I used to use chrome, and whenever I type "f" in the address bar, facebook.com will be autocompleted, so I can just click enter to go to facebook, rather than typing out the entire address or to look for it and select it physically on a list.
one thing though, with this addon, the first letter always leads to a random word, for example, when I type "r", the word republicans would show up. Would be nice to just autocomplete url addresses.
another thing i noticed is, even though I don't have the "always have the first result" selected, when i search for something through the address bar, the top result in the list is automatically selected.
