Rated 5 out of 5 stars

Firefox 3 doesn't really incorporate all the features of this add-on. Here is an example of what I mean:

A lot of websites use the www before the domain name (ex. www.yahoo.com). However, when I type an address into the address bar, I don't type the www. I just type yahoo.com.

In Firefox, it doesn't find the matching URL, even though I've looked at Yahoo's homepage many times and it's in the history. And editing the about:config to set "browser.urlbar.autoFill" to true (as some people claim) does NOT do the trick.

With this extension (in Firefox 2), though, I could type just yahoo.com and it would autocomplete it for me.

An updated version for this extension would be great!
