I currently use Google as my search engine, and every time I use it I get a rash of unwanted advertising crap at the head (top) of the search results. I know I can update my "interests" preferences in Google to "target" the ads, but I want to get rid of these pesky nuisances altogether. I was using Google SE on Firefox 77.0.1 for months, with any advert in results (always started with Wikipedia's article on search topic), but now there are intrusive ads results first. Why?
