I USED TO BE ABLE TO BLOCK NUISANCE WEBSITES THAT WOULD JUST SHOW UP ON MY TABLET LIKE HILLSDALE COLLEGE. NOW I CAN'T FIND THAT SECTION..

I USED TO BE BOTHERED BY WEBSITES THAT COULD JUST OPEN A NEW WINDOW ON MY TABLET. I FOUND I COULD BLOCK THEM AND STARTED TO DO IT EVERY TIME I ENCOUNTERED ONE. IT WORKED GREAT! LATELY, I HAVE BEEN GETTING SOME FROM HILLSDALE COLLEGE AND I BLOCKED ONE YESTERDAY. TODAY I GOT ANOTHER ONE FROM HILLSDALE WITH A DIFFERENT ADDRESS AND WHEN I WENT TO BLOCK IT, I COULD NOT GET TO THAT SECTION. WHERE IS IT?
