When "http://" is in front of a V3 link, Tor browser will search the text after "http://" on duckduckgo or any default search engine you use.
When "http://" is in front of a V3 link, Tor browser will search the entire link on duckduckgo, copy and paste the link below straight into the Tor browser URL field and click GO. If the user is trying to keep their hidden service secret, this bug will cause duckduckgo to see the unencrypted link, allowing attackers to easily find their hidden service if DuckDuckGo is compromised. http://ozmh2zkwx5cjuzopui64csb5ertcooi5vya6c2gm4e3vcvf2c2qvjiyd.onion
