Google昨天发布移动版Chrome，今天又对桌面版本进行升级。1月以来，Google就在测试新功能，升级后的Chrome浏览器将具有这些新功能，当中最为显眼的是omnibox预渲染功能和安全功能。通过omnibox功能，Chrome可以整合搜索地址栏，自动记录访问的网址，在后台预渲染页面，加快显示。在使用时，它让Chrome显示页面的速度更快，但实际上只是在后台加载。下载:Google Chrome 17 Stable
　　



　　新浏览器还增强了安全功能，它可以扫描下载文件，查看是否有恶意软件。如果存在风险，Chrome会提醒用户。

　　关于Chrome OS操作系统，Google承诺会进行改进，它会增加新图像编辑器。
