It does not work on Bing.

one of the most useful extensions. how is it not more known???

Perfect! I use Bing as my default search engine and it works - and it works really well!

Fast and accurate. Redirects all the searches before loading the initial search result, which is GREAT. Tried too many other extensions that would for (eg) `!w bubble` first show a glimpse of the google search results before going directly to the Wiki page with the information

This extension is really simply perfect. It redirects all queries starting with an exclamation point to duckduckgo and works great.
