Have you ever found yourself on a web page but you can’t find or click an arrow to go where you started? I have! Sometimes my arrows disappears like a picture above and i get bummed. This solved my question.
Click on View in the menu bar and select Customize Toolbar.
Then drag the Default Set on to the tool bar space at the top of the Safari page.
How does it disappear to begin with?
When you click Hide Toolbar on your View button. There you have it.
