When we click on link with target="_blank", a new page in a new tab can change our previous page on the previous tab. To avoid this effect, we can use rel="noopener" but too many websites not using this ability yet. And we can't affect them. This is a very simple Google Chrome extension that does only one thing: sets window.opener on every page to null before page loading is started. Despite the fact that websites use rel="noopener" or not (by the way Google search doesn't use it) we can keep calm - without window.opener this attack can't affect us.
