1. Open Safari on the iPad or iPad
2. Tap and hold on the tab icon, it looks like two overlapping squares in the top right corner
3. Choose “Close Tabs” from the dropdown menu that appears, the item selection will also display how many total tabs are open in Safari
The feature exists on iOS for both iPad and iPhone, though it may look slightly differently depending on the screen it’s displayed on, nonetheless the feature is always accessed by a long tap and hold on the browser tabs button.
It closes every single browser tab that was open in Safari, leaving you a blank slate to open new tabs as needed. This can be particularly nice if you wind up with dozens of tabs open in Safari, something which is fairly easy to happen as you browse over time.
