One of the highlights of Apple’s latest mobile OS “iOS 15” is the “tab bar” feature added to Safari
The “tab bar” is a bar that doubles as a search window, address bar, and tab selector switch. Since it is displayed at the bottom of the screen, you can easily reach your finger with one hand, and you can switch tabs intuitively by swiping, which is very convenient once you get used to it.
However, some users may feel uncomfortable with the display because the search window (address bar) that was previously displayed at the top has moved to the bottom.
If you want to return to the same display as iOS 14 or earlier, you can set it by tapping “Single tab” from “Settings” → “Safari”.
Note that if you set the same “single tab” as in iOS 14 or earlier, you cannot use tab bar functions such as switching tabs by swiping.
