I wanted to write for a long time, but it was forgotten. Increasingly, fashion websites ask them to click on them or similar when they call on them. But the most fun is that the screen when popping up the window is obscured and there is nowhere to press.
A cross is not always present. What to do ? First press the treasured button esc which means cancel, usually in the upper left corner of the keyboard. The truth is this does not always help, there is a browser window popping up like you really want to leave the site or resource? It's frankly frustrating for me. Of course you can lock windows, but you need and be able to cancel. Block add-ons for browsers and run java scripts, but many resources without them simply will not work correctly. It's not right to argue that anti-virus programs can fight with windows. To do this, there is a special software.
