Only 1 step short of being a perfect 10 Rated 4 out of 5 stars
This makes navigating a domain so much easier. The only problem is that the changelog says it added subdomain detection for Firefox 2. I don't know about previous versions, but I'm using Firefox 2 and apparently it is not working.
So, for example, I'm at addons.mozilla.org, and there's no way I can just click in 'mozilla.org' to be taken there, as it linkifies both domain and subdomain together.
Another related annoyance is that it doesn't detect an embedded anchor as a new link. So, for example, I'm at http://en.wikipedia.org/wiki/Science#Scientific_method, and I can't go back to the top just by clicking "Science", as it selects Science#Scientific_method as a link.
I actually don't know if this is possible, but this is the kind of function I was hoping for with this extension.
