Firefox could not install the search plugin from "https://addons.mozilla.org/firefox/downloads/latest/161972/addon-161972-latest.xml?src=dp-btn-primary" because an engine with the same name already exists.

Have duckduckgo addon with Mozilla with home computer, but it will not load here at the shop...why?

Thanks

Do you see this plugin in the searchplugins folder in the Firefox profile folder?
