This issue has nothing to do with Pop-up ads.  You can't print and invoice or an estimate without an error coming up.  Instead of bringing up a new window, the system now opens up a whole new tab everytime you want to print.  This is a recent phenomenon, and it started the week of Thanksgiving, I am in agreement that this is due to an update or a coding that someone did on Quickbooks end, not due to operator error on our end.   I have attached the error.
