On two different sites that use fairly high security (for example, www.experian.com), I have been unable to find a logout option when I was ready to end the session. It's hard to believe that the sites don't have a logout. I have not tried other browsers with these sites, so I don't know if this problem is unique to Firefox. Is there a workaround for this situation? Am I missing something? Merely closing the browser does not end the session. Any advice would be greatly appreciated.
