Im trying to install Firefox search engine on iphone

Hi, Firefox is a browser, not a search engine. So I guess you're trying to install Firefox browser. But what is the question?

You appear to be running the Firefox 150.3 web browser on iOS/iPadOS to post this question. Mozilla the makers of the Firefox web browsers for desktop and mobile versions does not have a search engine of their own. https://support.mozilla.org/en-US/kb/enable-or-disable-search-engines-firefox-ios https://support.mozilla.org/en-US/kb/change-your-default-search-engine-firefox-ios
