在Chrome 69版本中，Google尝试“简化”登陆选项，一旦用户通过谷歌账号登陆Gmail或者其他谷歌服务之后，那么就会自动登陆Chrome浏览器。此举遭到了很多用户的吐槽，对此在新版本中谷歌对其进行了调整，提供了三项调整：

● 正如下图所示的选项，允许用户关闭网页登陆和浏览器登录之间的账号绑定。如果用户禁用这个选项，那么登陆Google或者服务，那么登陆账号之后并不会登陆Chrome。

● 对用户界面进行调整，让用户更清楚的知道同步状态

● 在Chrome 69中在Cookies清理之后依然保留Google账号Cookies，以便于用户保持登陆状态。不过在Chrome 70版本中会删除所有cookies。

虽然这三项改变带来了某些改进，但第一项改变并没有解决主要问题：自动登陆默认情况下依然处于启用状态。

此外Google还在Chrome 70中新增了一系列新的功能。这款拥有10亿用户的浏览器在Windows 平台上现在支持Progressive Web Apps（PWA）。用户可以从开始菜单中触发这些应用，并且能够和其他已经安装的应用一样运行。

AV1是Alliance for Open Media的免版税编解码器。与编解码器VP9相比，AV1的压缩效率提高了30％以上。Chrome 70新增了AV1解码器（不包括编码功能）。 用户可前往YouTube的TestTube页面，选择 “Prefer AV1 for SD”或者“Always Prefer AV1”，然后从 AV1 Beta Launch播放列表中播放片段。

此外Chrome 70还修复了23处安全漏洞，包括：
