Title: Not much more to say than the title. I enabled ModHeader to test something a couple days ago and started noticing the same add showing up in the sidebar on both Google and Bing. I keep a constant vigilance with uBlock Origin and denying all 3rd party cookies.<p>Since that was the only extension I&#x27;ve modified recently, I disabled it and refreshed a search page and voila, the ad is gone.
