DuckDuckGo

Opera now includes DuckDuckGo by default in its desktop English versions (since 11.60). If you have one of those versions, you can actually use DuckDuckGo by just doing 'd <search term>' from the address bar, or by choosing DuckDuckGo from the search bar (in the upper right).

For other desktop versions, you can add it using this procedure:

1. Right-click the DuckDuckGo search box (in the page).
2. Select Create Search.
3. Enter d for keyword.
4. Check Use as default search engine and User as speed dial search engine (if you wish).
5. Click OK.

If you have a custom URL, you must put "q=%s" at the end to make it work.

To set DuckDuckGo as your start page:

1. Open the Opera menu (top).
2. Go to settings/preferences.
3. Under homepage, click Use Current.
4. Click OK.

These (non-Company) extensions also use DuckDuckGo:

• DuckDuckGo by Shwetank Dixit (open source) - adds a button to the toolbar .
• DDG + Google Suggest by Nathan Friedly (open source) - adds Google auto-complete.
