I have used Firefox as browser for years. Yesterday, my default search engine in FF was changed to Bing. The settings in FF clearly show my seach engine is duck duck. I cannot open duck duck, because bing will not go away! I tried chatgpt. It gave me three good suggestions and walked me through it, but no success. the AI says its some sort of embedding in an add on or extension. This is well beyond my computer ability. Can you suggest any way out of this? Bing is simply awful!!
