This is a little know Safari feature. And a very useful one, if I may add.
Did you knew that you can close all sites you have opened on Safari with in just one action? Yes, that’s a thing on iPhone and iPad.
Swiping tabs left or right is the most well know option closing tabs on Apple’s browser on the mobile devices. But there is a faster way to close all tabs at once.
Long press the tab button until a small menu is shown. Now tap “Close all X tabs” and confirm.
You’re done. And you’re welcome. 🙂
Here’s a short video showing (hopefully) hot this works.
