To add this search extension to Firefox:

1. Navigate to about:config.
2. Set the devtools.chrome.enabled preference to true.
3. Open Browser Console.
   Caution: that’s not the Developer Tools console. It’s something entirely different.
4. Paste the following code snippet into the Browser Console:

await Services.search.addOpenSearchEngine(
  'https://gist.githubusercontent.com/claui/30a5ee2dc2c2389cd09d9595310823f0'
    + '/raw/578e5a3b22889e069556ed8b00c991d7713400ce/opensearch-twitter.xml',
  null
)
