If you haven't already done so, you may want to check out support.mozilla.org (or even use the Bing AI!) to review what you can do with search engines in Firefox. I made this for myself, after figuring out how to send queries directly to the Bing AI page, so I didn't have to go to bing, wait, select chat, wait, then type, to do every query. Instead, I can trigger the address bar, type chat (or whatever keyword customized), type in my question, and it's done in a single action. Respectfully, I'd say that's pretty useful.
