I am sure you know the problem, and I assume it's difficult to fix or you would have done it by now. Many web sites try to make it difficult to exit by having endless dialog boxes appear when you try to close the tab. "do you really want to leave" "do you really really want to leave". It would make browsing easier, and less worrisome if it were possible to close that sites tab without ever touching their dialog boxes. You have a great product thanks for your efforts especially on security.
