Using: Windows Vista OS and Mozilla Firefox 4.0.1. BT Yahoo has a login page that allows the user to create a seal on the login page to help identify a valid website. I am th main account/admin and I have no issues; everything looks good and correct. My husband has a sub account, but there is no seal showing nor is there a clickable facility to create a seal. This occured immediately after upgrading to Firefox 4 and unstalling and reinstalling did nothing. Had no issues prior to upgrade. Appreciate any helpful suggestions.
