Whether I sign in using Yahoo Classic or the New Version, an advertising video loads automatically in my Inbox and every other empty folder.

I can stop it and X out of it but it still starts automatically then next time that I sign in.

The only way to stop the video from loading upon sign-in is to email myself and save the email in each folder.

Is there a way to permanently stop videos from loading automatically upon sign-in or is doing what I did the only way to stop them from loading?
