Macs Safari browser has a convenient feature: lets you use tabs for web pages. The advantage of tabs is that they allow you to keep multiple websites open and easily accessible without messing up the screen with a host of browser windows.
To open a new tab Click the New tab button (a "plus" character) near the top right corner. To change the page that opens in new tabs, select Safari> Preferences, click General, click "New Tabs Open With", and then select an option. To open a page in a new tab, command a link on a page, a Favorites icon or a thumbnail for Top Sites.
Safari also lets you "pin" tabs. By linking a site, you put the site's icon in the upper left of the tab so you can pull up the site with a click. Pinned tabs are persistent across all Safari windows, even when you release the browser. Synchronized content on dropped tabs across windows, including video. To cut a tab:
In the Safari app on your Mac, drag the tab with the site you want to stick – for example (ahem) https: //blog.macsales.com – to the left of the page tab.
When the tab shrinks and displays the site's icon or initial, release it into place.
You can also select Window> Pin fan, or Control-click on a tab and select Pin fan.
To remove a landline, drag the dropped tab to the right of the tab.
You can also select Window> Loosen Tab, or Check-click on an attached area, and then select Solution tab.
You can also reorganize pinned tabs. Click and hold on a tab and drag it before or after another attached tab and it will fall into place.
