Google's browser is based on the WebKit rendering engine that underlies Safari. It runs only on Windows for now. Mac and Linux versions are in development.
To fight malware and phishing attempts, Chrome is constantly downloading lists of harmful sites. Google also promises that whatever runs in a tab is sandboxed so that it won’t affect your machine and can be safely closed. The browser has an address bar with auto-completion features. Called ’omnibox’, Google says it offers search suggestions, top pages you’ve visited, pages you didn’t visit but which are popular and more.
