I want duckduckgo removed as my browser how do i do this

Type about:preferences#search<enter> in the address bar. You can select any search engine to be your default from here.

You can also remove any engine from here.

If there is still a problem, Please explain the problem in detail. What happens? What is/are the exact error message(s) ?

DuckDuckGo is a built-in search engine and can't be removed. You can only hide it.
