The text from the post here
As part of our ongoing commitment to security analysis and testing we engaged SmartWare to test the effectiveness of our Phishing Protection feature. Firefox 2 Phishing Protection and IE 7 Phishing Filter were tested using know phishing sites as evaluated by the community at PhishTank. We picked PhishTank as a data source because it is completely independent of the feeds that we use to create the URL block lists. Since IE might either warn or block, either result was counted as a block for the purpose of this test. To make the test as fair as possible we counted only URL test cases where both IE and Firefox were tested within a 15 minute window and switched the order of which browser was tested first. The results are posted here.
