Firefox on iPhone blocks pop-up windows by default, which is usually what you want. Some sites, such as banking or school portals, need pop-ups for sign-in or downloads. You can turn the blocker off in Firefox settings and turn it back on when finished. The iPhone 7 can run up to iOS 15, and newer Firefox versions may require a newer iOS.
Quick Answer
Open Firefox, tap the menu (three lines), tap Settings, and turn off Block Pop-up Windows. Turn it back on after you finish with the site.
