Hi Theo

I am sorry but I do not understand your question. Firefox for iOS does not have an AI overview.

Hi Paul, I’ve attached a screenshot and believe that this is an AI overview. If it’s not, what would you call it and do you know how to turn it off? Thank you for your assistance!

You should be able to go to https://www.bing.com/account/general and scroll down to Chat response on result page. If you want to disable it, tap on Auto (Default) and select the Off option. When you’re done, tap Save at the bottom of the page.
