yahoo mail "please verify your password" when opening new tab


When I sign in to Yahoo mail on the first tab, it works fine. When I open an additional tab, it always asks "please verify your password". In the past, I have always been able to open a new tab and stay signed in. I had to reinstall Win xp and now it always prompts for my password when opening a new tab. I have tried clearing cache, history, cookies and still have the issue. I tried different versions of FF, including FF15 and16 and none work. I have also tried restoring FF to default setting and restarted with add ons disabled. Additionally, I tried setting the network connection to "no proxy". Nothing has worked. Any other suggestions? Thanks. IE and Chrome work fine and I do not have this issue.

You should install and use the current Firefox 16 release as soon as possible.
Your current Firefox 5 version has a lot of security vulnerabilities.

Did you try a new profile?

Did you check the date and time on the computer?

Make sure that your security software (firewall, anti-virus) isn't blocking cookies if the settings in Firefox are correct.
