Google, as promised, has turned off the anti-phishing tool used in Firefox 2 as of 20th January. The anti-phishing tool would block sites suspected of hosting identity theft scams.
Recent Firefox build 2.0.0.19 and 2.0.0.20 have had this feature removed, but there are still thousands out there using earlier versions.
Mozilla is urging Firefox 2 users to upgrade to Firefox 3 as soon as possible. Firefox 3 includes a newer version of the anti-phishing protocol provided by Google.
Firefox 2 users can upgrade to Firefox 3 by selecting ‘Check for updates’ in the help menu, or can download the update manually from the Firefox website.
