Firefox 2 no longer supported - phishing filter disabled | Wiz's Computer and Website Security Blog

If you are still browsing the Internet (and reading this) with Firefox 2.x, you need to know that support for it has ceased. Mozilla.org is no longer releasing any security updates to this line, which ended at version 2.0.0.20, in December 2008. With that final security update an existing security feature was disabled. Mozilla has turned off the anti-phishing filter built into Firefox browsers, from 2.0 up. This was done at the request of Google, who maintain the databases used by the phishing filter. However, the anti phishing filter is alive and well in the new series 3 Firefox browsers. For your continued security I recommend that you upgrade to Firefox 3.x as soon as possible.

If you have an older version of Firefox 2.x and the anti phishing filter is still enabled on it, I have bad news for you. On Monday, January 19, 2009, Google turned off the phishing website blacklist for Firefox 2.x browsers. Even though your browser may show the anti phishing filter as active its database is no longer being updated. This gives a false sense of security where none exists. Phishing websites typically have a useful life of between 3 days to two weeks, before they are reported and taken down by hosting providers or ISPs. If your anti phishing filter is not receiving regular updates you will be completely out-dated in a week or two. The websites in your blacklist will probably be inactive (as phishing sites), but newly discovered sites won't be added to your database.

You have some tough choice to make if you want to have Firefox browser protection against phishing attacks via compromised websites. If you choose to not upgrade to Firefox 3.x you should disable the setting "Tell me if the site I'm visiting is a suspected forgery" in the Security preferences section of Firefox 2.0's Options dialog box.

Here are your anti-phishing security options.

Upgrade to Firefox 3.x which Google is supporting with new anti phishing updates (Recommended)

Install the Netcraft Toolbar for Firefox

Install the McAfee SiteAdvisor Toolbar for Firefox

Install the Trend Micro Web Protection Add on (beta)

Trend Micro Internet Security (PC-cillin)

All of the above options will detect and prevent access to known phishing websites. The Trend Micro programs also block access to malware distribution or exploit coded websites.
