I've had this problem for a long time on Linux where the default DuckDuckGo search plugin shows no search suggestions and I cant even replace it with this https://addons.mozilla.org/en-us/firefox/addon/duckduckgo-ssl/?src=userprofile I instead have to use the non-JavaScript version https://addons.mozilla.org/en-us/firefox/addon/duckduckgo-html/?src=userprofile which doesn't support Web Of Trust and other features. So I would like to know is there a way to change the the default DuckDuckGo search plugin in about:config so that it supports search suggestions?
