### Can you hide Firefox on iPhone?

Yes. On iOS 18 or later, touch and hold Firefox, tap Require Face ID, then Hide and Require Face ID. It moves to the locked Hidden folder at the bottom of App Library and leaves search results.

The iOS lock and hidden status don't sync with iCloud; set them on each device. Firefox has an iPad app, so repeat the steps there.
