good guy Chrome, where after the 2nd click there's a checkbox called "prevent this website from creating additional dialogues"... I guess, those ancient prank sites don't work anymore today...
It's been loading for over 10 mins without me clicking anything. The amount of JS, which in this case forms alerts, on that site is responsible for the slowness. It's either that or images being transferred from sites I've never heard of, or many HTML errors.
Edit: it was taking to long to load, so I just closed the tab.
