Hi there, I'm assuming you meant changing your device's default browser from Google to Firefox for iOS. To do this, follow these steps: # Head to the Settings app on your iOS device. # Scroll up just a bit, and then search for "Firefox". # Click on the Firefox browser. It should be the first option, but make sure you click on the right one. # Somewhere in the middle-bottom section of the page, there should be an option called "Default browser app". Click on this and then select "Firefox". I hope this helped! If it did, please mark this as the solution so that others can find it. Otherwise, have a great day!
