To set up a private session link in Firefox:

  1. Enter about:config in the address bar and press enter
  2. Add a new preference called browser.urlbar.update2.engineAliasRefresh, of type Boolean and value true. (This will enable the button to add a new search engine in about:preferences#search)
  3. Open this URL in your search bar: about:preferences#search
  4. Click the "Add" button below the table under the heading "Search Shortcuts"
  5. Enter the following values:
    • Search engine name: Kagi Search
    • Engine URL: https://kagi.com/search?token=TOKEN&q=%s (replace TOKEN with the token found in your private session link​)
    • Alias: kagi
  6. Select the new "Kagi Search" as your default search engine using the dropdown at the top of this page.

There is currently no way to manually set the 'Search suggestion API' for a search engine in Firefox desktop. Installing the extension does allow you to use suggestions.
