Diggler is a small but powerful add-on for Firefox and Mozilla. It adds a menu button next to the address bar with actions relevant to the current URL, for example to step out to the parent directory, or to visit the equivalent ftp URL, or to visit the site in archive.org. A single click on the menu button also clears the location bar (much like the one in Konqueror) - useful for keyboard free browsing.
