Search the web from Spotlight (<kbd>⌘ Command</kbd><kbd>Space</kbd>) by entering search text and pressing <kbd>⌘ Command</kbd><kbd>B</kbd>. The expected result of opening the default web browser (Firefox) and completing the web search occurs. However, the web search engine uses Google rather than the default (DuckDuckGo).

How can I set it so the search is done with my chosen search provider?
