Apple's free Safari web browser comes installed on every Mac and you can download a version that runs on PCs. When you visit websites with Safari, you can use the toolbar to do tasks such as reload a page, zoom the text, print the page, look at your history or bookmarks or open a new blank tab. The toolbar takes up space in a strip running across the top of the Safari window. If you want to have a little more room in the window to see websites, or if you find the toolbar unnecessary or distracting, you can easily hide it.
Double-click on the Safari icon to launch the web browser.
Click "View" from the menu.
Click "Hide Toolbar." The toolbar will disappear.
