Xfinity third-party ads in email window are stealing cursor focus!!

Frequently, I open my browser window to quickly compose an email. But the third-party ads to the right of the email window steal my cursor away from the active window (which in my case is the compose window). This is a usability nightmare. Any time the ad window refreshes, the cursor becomes inactive until I click back to the email window. PLEASE fix this problem!! It's bad enough that I pay a lot of money to Xfinity every month and then have to put up with third party ads that clutter up the login screens and literally force the user's attention to these ads in their email windows by hijacking the cursor. This is fixed by good coding. I challenge your developers to fix it.
