Edited original as it was broken in my Tampermonkey on Google Chrome Canary (haven't nor do I intend to test if it is just because of my setup); search engines wouldn't add to the bar. So I just changed the defaults to my preferred, Privacy friendly and/or FOSS search engine links. Search engine addition still does not work. Forked from original at https://openuserjs.org/scripts/tumpio/DuckDuckGo_Extended mostly to help me learn and understand the code
