Strange new screen when trying to access COX webmail regardless of device type

I had the same screen for a moment,  clicked the back arrow on my browser thinking I had accidentally clicked something.  It then logged me on to view my webmail.  I tried to signout using the icon on the webmail toolbar,  but it just keeps reloading the page.  I had to close out of the browser completely,  Opened up browser again,  clicked my bookmark for Webmail,  logged in like normal,  but it still won't let me sign out.
