Netcraft Toolbar for Firefox provides comprehensive security information on the phishing efforts of Web sites, though the tool doesn't actually block sites deemed guilty. Its database stores the attributes of any given site and offers ratings based on reports made by users. A simple bar attaches itself to your Firefox browser window, where you'll be able to see how long a visited Web site has been around, its ranking among the most visited Web sites, a detailed site report, and the managing hosts history. Selecting a topic on the toolbar displays a corresponding page where you can drill down for more information, reading up on the history of the site and its Web server. You can report phishing sites for analysis and bugs, though you can't actually block a suspected site. Still, Netcraft Toolbar for Firefox is great for those wanting to know the background of any given Web site.
The Netcraft Toolbar uses Netcraft's enormous databases of Web site information to show you all the attributes of each site you visit on the Web, including the sites' hosting location, country, longevity and popularity. It also mobilizes the Netcraft community into a giant neighborhood watch scheme to empower the most alert and experienced members to protect the vulnerable against fraud and attacks.
