谷歌浏览器v80正式版主要更新，加强网页登陆安全性，调整第三方Cookie策略。引入SameSite cookie更严格的安全分类，只有HTTPS、且SameSite设置为None时才允许第三方调用Cookie。其实早在Chrome 51中，SamSite Cookie首次引入，其设计用来阻伪造的止跨站点Cookie请求。

谷歌浏览器v79正式版主要更新，对密码检查工具的内置支持，通过安全浏览API实时将恶意网站列入黑名单，可预防网络钓鱼的常规可用性，禁止加载HTTPS“混合内容”，支持选项卡冻结，Chrome Sync个人资料部分的新界面，以及对后退缓存机制的支持。

谷歌浏览器v78正式版主要更新，带来了多项功能和改进，在Windows 10（版本 1511+）系统上默认启用。还引入了内置的密码检查工具，目的是如果在用户登录期间发现异常就会发出提醒，允许用户在新标签页中添加壁纸，以及安装来自于Chrome Web Store上的主题。
