Rated 5 out of 5 stars

I can't believe that Mozilla have broken searching from the address bar, especially since they have an ongoing contract with Google.

Anyway, same comments as other users above. Installing this fixes the broken searching from the address bar.

Minor snagging - having upgraded to Firefox 23 and installed the Keyword Search add-on, I have now got DuckDuckGo set up as one of my search engines. Don't know if inclusion of DuckDuckGo was part of the Firefox 23 build, but if not then it should be flagged up when the add-on installs.

This review is for a previous version of the add-on (1.0.2.1-signed). 

I do bundle DuckDuckGo with this add-on. You can delete it if you don't want it. I'll make that clearer in the description.
