In case you didn't hear, FireFox
2 is now available for download. Here's one of the new features...
Built-in phishing protection: Phishing Protection warns users when they
encounter suspected Web forgeries, and offers to return the user to their home
page. Phishing Protection is turned on by default, and works by checking sites
against either a local or online list of known phishing sites. This list is
automatically downloaded and regularly updated when the Phishing Protection
feature is enabled.
