I’ve previously had this problem and now it’s back. I log on to mumsnet and read one thread say, and when I hit back this ad comes up in full screen instead. It’s impossible to go back from it. The only thing I can do is close the window and start over, but I only get one click before the ad comes back. Also it’s clearly a phishing ad purportedly from my internet provider about a “prize”, but badly spelt and worded. Am using safari on an iPad.
Link to the ad I see:
