I want the same behaviour in the URL bar drop down as the search bar drop down, meaning that when I click a search engine, it immediately searches with it instead of doing search suggestion queries. How can it be done in modern Firefox? The search bar should also have its own separate default search engine so you can immediately swap between 2 primary search engines without needing to select one from any drop down at all. https://support.mozilla.org/en-US/questions/1318332
