Last year, my brother told me that chrome under Windows got hung this way. He was looking at some torrent site or whatever. He kept clicking close for what he said seemed like an eternity before it gave up.
I asked for the link because I was curious if non-Windows devices can get hung.
I tried it on my iPad, using Safari, then Chrome. Some "FBI" screen came up both times, so I closed it, both times, and that was it. Evidently it dies on the iPad.
I opened up a Linux VM, and tried the link using Firefox under Linux. The same sort of "FBI" screen appeared, but I could not close Firefox no matter what I tried. So I just closed the Linux session, then restarted it. I re-opened Firefox and the page did not re-appear.
I will not try it on my MacBook.
