DuckDuckGo Onion Search for Firefox

July 30th, 2021

DuckDuckGo offers a Tor .onion V3 search URL over here:

In order to add this to Firefox as an OpenSearch engine to let you default to using the DuckDuckGo Tor search, you need to jump through a few hoops, though. I must have done so a while back for the V2 URL, and since I can't find an up to date search plugin, let me use my blog as a memory bank for the next time I want to update the URL of a custom search:

First, create a .xml file like this:

<OpenSearchDescription xmlns=""
  <ShortName>DDG Tor</ShortName>
  <Description>Duckduckgo Tor</Description>
  <Image width="16" height="16" type="image/x-icon"></Image>
  <Url type="text/html"
    <Param name="q" value="{searchTerms}"/>

Stash that XML file somewhere convenient, like here.

Create a .html file that contains in the HEAD the link rel="search" meta tag pointing to that URL:

<link rel="search" type="application/opensearchdescription+xml"
    title="DuckDuckGo Tor" href="">

Now you can click on the search bar at the location of this HTML file and then click the search icon with the little green plus sign:

from the browser's search bar

After this, you can then select "DuckDuckGo Tor" as the default search engine in Firefox under about:preferences#search:

After that, any new search in the address bar will use the shiny new DuckDuckGo V3 Onion search - yay!

And just so you don't have to jump through all these hoops, you can simply add this Onion search as described above right here from this blog post. Enjoy!
