This happened recently to me, it was kinda crazy because I always thought I was better than this. No idea what extension it was but I have Google as the default search engine but CloudFlare gave some notice that whatever-search.com was down and I was like wtf!

They used windows group policy to lock down the search engine so I couldn’t change it from Yahoo too. But it still would up taking me to Google. It was only on one of my mini PCs I rarely touch so I never paid attention. Going to install debian on that guy today and make it headless!
