Is there a way to close Website Blocked windows automatically?
We only act on the DNS level, so we don't even see the actual HTML, it wouldn't really be possible for us to afffect actions on the browser, we just don't have that kind of access. Other browser plug ins may be able to collapse down blank elements, but that would be a separate product and solution.
It might be possible to add in some javascript to close the page, but then any ad that might get replaced with the blocked page instead of the empty block page would get its page closed, which is probably not what you want.
