Private Mode appears to function just as incognito mode does in Chrome, allowing you to open a private window that does not record your browsing history, cookies or have any affect on other windows open. Private Mode is accessible from the top menu bar, and the private windows have a noticeably different appearance so that you know you are privately browsing.
Safari also has a new tab view, with individual stacks on the homepage and smooth scrolling for tabs. Apple has also integrated Spotlight search into the Safari address bar, allowing you to preview articles and searches before clicking through to read an entire article or website. Just like Private Mode, this is another feature that brings Safari on level with Chrome.
Safari now has improved sharing options for RSS and webpages, accessible from a dedicated sharing menu. Users can subscribe to pages in a new feature called Share Links, or share over Facebook, Twitter, LinkedIn, Messages, AirDrop or other services. Like in past versions of Safari, you can also add pages to your Reading List or email.
