The Toolbar community is effectively a giant neighbourhood watch scheme, empowering the most alert and most expert members to defend everyone within the community against phishing frauds. Once the first recipients of a phishing mail have reported the target URL, it is blocked for community members as they subsequently access the URL. Widely disseminated attacks (people constructing phishing attacks send literally millions of electronic mails in the expectation that some will reach customers of the bank) simply mean that the phishing attack will be reported and blocked sooner.The Netcraft Toolbar for Firefox can be downloaded here.
