Safari浏览器在很大程度上仍然在运行OS X Yosemite相同, 但苹果增添多项功能，并提出了一些关键的调整，使古老的网页浏览器更加智能和一点更易于使用.
智能搜索栏, 姓地址栏, 是大部分的Safari浏览器8的新功能和改进，可以发现. 最明显, desktop Safari now follows the mobile Safari convention of hiding all but the root domain of a URL — users need to give the search bar focus by clicking in it to reveal the full URL.
一些修改开始发挥作用，一旦用户是在搜索栏中键入. If the user is currently on a web page, clicking in the search bar will result in an icon-stuffed dropdown menu of the users’ favorite and most frequently visited sites. If the user is already at the Favorites or Top Sites screens, 然而, nothing will happen until the user begins typing.
In either case, once some text has been entered, the bar will default to a Mavericks-style dropdown of Google suggestions and history shortcuts. One notable addition in this view is a new quick links feature that integrates Spotlight suggestions, such as Wikipedia entries, directly into the dropdown.
The most glaring addition to Safari 8’s tabbed browsing is the new Mission Control-like tab overview. Activated from a dedicated button in the upper-right hand corner, the new look gives a birds-eye view of every tab currently open in that Safari window, grouped by website.
Safari浏览器8的标签栏也有一个稍微不同的行为时有大量的标签打开的, 改变翼片的宽度在任一端, 具体情况取决于当前的重点选项卡所在. 用户可以通过自己的触控板或Magic Mouse鼠标滑动一侧到另一侧通过揉成向上滚动标签, allowing them to see tabs which are out of view — this replaces the pulldown menu that previous appeared on the right-hand side when too many tabs were open.
Private Browsing has been expanded in Safari 8, with users now able to create Chrome-like private windows while allowing other windows to remain open. Previously, going private meant taking every window private at the same time, an inconvenience for many users.
Opening a private window causes the smart search bar to turn a dark gray, similar to the paradigm used in iOS. A short message confirms that any visited pages, search history, or AutoFill information used in a private window won’t be retained.
Safari的清除历史记录功能是显著改造的受益者. 在另一个让人联想移动Chrome浏览器, 用户现在可以选择清除他们的历史过去一小时, 今天, 昨天和今天, 或全部时间. 有趣的是, it appears that Apple is set to synchronize browsing history on every device by default — clearing history on a Mac will also clear history on any other device signed in to the same iCloud account.
苹果浏览器 8 带来的共享选项的大幅扩张, 其中许多可以利用OS X的新系统范围的扩展功能，可定制. 另外, 共享现在是半透明叠加做 - 选择一个共享选项将导致Safari浏览器窗口 “胀” 略作为截图被取, 那么这将使得其进入共享覆盖，而窗口的其余部分变暗.
