Close all Safari tabs on iOS 7 with just two taps!
With the new Safari tab interface on iOS 7, you can have multiple tabs open at once. It is simple to close each one individually, however closing 10 to 15 tabs in one go could be time consuming! There is a simple way to close all tabs at once, just follow these steps!

Open Safari and view your currently opened tabs. Instead of swiping each open tab away on your iPhone, select Private at the bottom left of your screen.
You will then be asked whether you wish to keep these current tabs open, or close all which is the option you need to select.
If you then press ‘Private’ again, you can disable private browsing and all your tabs will be closed.
Its as simple as that!
