Some users have encountered issues when trying to set DuckDuckGo’s Onion site as their default search engine in Firefox. If you're using Firefox with a Tor connection and prefer accessing DuckDuckGo through its Onion address instead of the standard URL, this extension could be helpful.
Just install the extension in Firefox, and when prompted to switch your default search engine, click "Yes."
