Safari Lets You Preview Tabs

Apple overhauled Safari, adding a handful of small, but significant features. You can now automatically translate a page in a foreign language. There’s also a new privacy reporting engine that tells what each webpage is doing with your data.
Our favorite change is how Safari handles tabs. Instead of automatically collapsing tabs, Safari now shows a preview of each tab. You can now see the contents of each tab as you scroll through them. These previews help you figure out the contents of the tab without needing to open it first. Just scroll through the previews and click on the exact page that you want to re-open.
