I noticed you have AdBlock installed, so just right-click on them and go to AdBlock and select "Block this ad".
Theres a option like "block a ad in this page" so I selected it. Then it asks me to push a sliker until its gone, but this slider has only two postitions, one in which nothing happens and the other one it blocks the whole page lol. I could block only the X button to close it tho. But the popup still opens, just without the close button.
