Cannot complete login using Firefox or IE 9

My users are not able to complete a proper login using Firefox 18 on a mac or IE 9 on a pick. After they create a login that does not allow them to see the content, they have to log out, clear cache, then login in again.

I have also tested with the new beta 3 with the same consistent results

here is a link to the video http://youtu.be/VglfExMd8NA

please advice

Thank you
