raise exception_class(message, screen, stacktrace)
WebDriverException: Message: Unexpected error launching Internet Explorer. Protected Mode settings are not the same for all zones. Enable Protected Mode must be set to the same value (enabled or disabled) for all zones.
問題原因：
保護模式的值不一致
解決方法：
所有的mode都要設置一致，要么都選，要么都不選

raise exception_class(message, screen, stacktrace)
WebDriverException: Message: Unexpected error launching Internet Explorer. Browser zoom level was set to 110%. It should be set to 100%
問題原因：
瀏覽器被放大了
解決方法：
設置為100%
