Why did my yahoo home page change yesterday Nov 16 2012. Hate it cannot put my favorites on homepage?

Yahoo keeps testing various product designs and features to "gain valuable feedback and insights from their users". Part of this process includes ongoing tests to identify how they can make the Homepage more useful and personally relevant. In line with Yahoo!'s standard procedure, they randomly expose test pages to some users. The issue you reported may be the result of such a test. The duration of tests varies from user to user, but emptying your browser's cache by deleting all cookies and temp files, then re-starting your machine, may restore the standard Yahoo! Homepage and prematurely end the test. If that doesn't resolve the issue, try to access the page using another browser. Note: if you clear the test page, Yahoo! will not be able to determine that you've already experienced the test, so it may appear again.
