How do you stop fake Amazon contest ads take over safari
I’m on an iPhone 7, iOS 11.2, browsing legitimate sites like nytimes.com and ESPN.com when these contest ads usually relating to Amazon or Comcast suddenly display and the browser URL changes to something other than the site I was on. Hitting the back button once or even twice doesn’t do anything, and you can’t edit the url directly. Only closing safari or clicking back repeatedly will get rid of it. I don’t understand how this can be happening on these sites, if it’s oroginating from the ad units they are running or it’s some kind of malware on my iPhone. Anyone with suggestions to resolve are much appreciated!
