Yesterday I started Firefox and got a question on Syncing; I think I answered "NO". All of a sudden Firefox disappeared, and I got "Bing-Firefox" browser. All my bookmarks were gone, and all the browser information presented me with "Microsoft" stuff. The Firefox icon is still on my desktop, but when I choose it the only thing I get is "Bing Shopping", "One Drive", etc. I don't want anything to do with Microsoft, or "Bing"; what happened? How do I get back to pure Mozilla Firefox? Thank you, Peter ''[Personal information removed by moderator. Please read [[Mozilla Support rules and guidelines]], thanks.]''
