A friend is having a problem with Taboola ads on her homepage. Using Ad Block Plus in Firefox has moved the ads from the sides to the middle-almost like a header. after running Malwarebytes scan Taboola ads did not go away. It reads: "Ads You May Like". While you can right click and "close' them-they are dimmed and still there. After signing in to her MS account there is a thing called Microsoft Personalized Ads-which I've never messed with and didn't understand fully. You can toggle it On/Off-neither removed Taboola.
I did find an article online saying that Ad Block Plus was being paid by MS, Google and Amazon to allow their ads. I also suggested that she use another home page.
