I'm in a site that has a pop up requesting a password. I don't have it and want to get out of it. I hit 'cancel' but the pop up immediately pops up, again, not allowing me to shrink and dispose of the site. I even tried hitting 'ok' instead of 'cancel' but the same thing happens....over and over and over, again. I tried powering down and then restarting but as soon as I go to the Safari browser, the same website/pop up is there insisting that I fill out the form. How the heck can I get out of this pop up and get rid of the website?? Many thanks.
