Once you're there, click the pencil on the last entry under "Search engines" (it's probably DuckDuckGo). Once you do that, a popup will appear. Populate it with the following information:
Field
Value
Search engine
{%server_name%}
Shortcut
{%server_name%}
URL with %s in place of query
https://search.shittyweb.org/web?s=%s
Once that's done, click
Save
. Then, on the right handside of the newly created entry, open the dropdown menu and select
Make default
.
