Previously I used Chromium/Google Search as my browser/search engine combo. When I did that I could type the following into the address bar to limit my search to a specific site:

site:www.example.com searchterm

Now I am using Firefox/DuckDuckGo instead. When I type the same command into the address bar I get this error:

Problem loading page

The address wasn't understood

Firefox doesn't know how to open this address, because the protocol (site) isn't associated with any program.

You might need to install other software to open this address.

If I type the site:... command into DuckDuckGo directly, it works. How can I make Firefox recognise the site: prefix as a command, OR what is the equivalent command in Firefox?

(I would strongly prefer to use the address bar rather than the search bar.)


Reverse the tokens:

searchterm site:www.example.com

By putting word:word at the beginning, Firefox assumes that you're typing a protocol and hostname.


Add ? in front of the query to workaround this problem related to Firefox.

?site:www.example.com searchterm

  • Even Firefox updated couples of time, it still cannot handle those queries gracefully while Chrome can.
