I had a website come up that said my system was locked and I had to pay money to get it unlocked. Additionally, there was a window with "Leave This Page" button and "Stay On This Page" button. Clicking the first button did nothing...I couldn't even exit Chrome. How do I prohibit all websites with this despicable behavior from loading? Or, better yet, how do I destroy their entire existence?
This is intended behaviour for many sites which may want you to make sure that you do not leave while filling a form or similar (askubuntu.com itself uses it). In all cases I've personally encountered, I could exit with the "Leave this page" button. Are you sure that this is not a coincidence or related to another problem or program?
