Rather than a single button, resetting your Safari browser requires multiple steps (such as emptying your cache and history). As a result, it will take some time to complete. This is what you must do:

• Delete all of your Safari histories.
• If you wish to make a reset on all of your devices, keep in mind that the process is different for Safari on an iPhone or iPad.
•  Open Safari.
  
•  Select 'Safari' from the top toolbar, then 'Clear History.'
  
• From the dropdown menu, choose 'All History,' then 'Clear History.'
