An easy to use yet very useful add-on for Firefox is Google Preview. This add-on inserts a thumbnail image of the Google search result beside the link. Not only does this add-on work with Google Search, but also on Yahoo! Search. This may come in handy when searching for a particular site you may have seen some time ago and forgotten its URL. Apart from the thumbnail preview of the search results, this add-on also adds a ‘Popularity rank’ bar below the link of each search result.
