To install Firefox on iOS/iPadOS you do so at the Apple App Store. You need iOS 16.0 or later to install. Google Play is for Android devices. https://support.mozilla.org/en-US/kb/install-firefox-your-ipad-iphone-or-ipod
If while on the Firefox page on Apple App Store it says OPEN instead of GET then that means you likely have Firefox installed and it should be as one your app shortcuts to start Firefox.
