I did a registry cleanup with CCleaner and when I open Yahoo Mail with Firefox 2, it won't open because my SSL protocols are disabled. I checked tools and they seem to work fine. I even had to go to about:config to fix that, but to no avail. It won't let me to go to Yahoo Mail. It also says in the Alert that this could be related to my browser's security registry. I deleted with with CCleaner. How I can identify this registry so I can log in to Yahoo Mail again?
