[UPDATE] The bug caused by 2 accounts tied to same phone number. After change phone number no more error.
https://www.zhihu.com bug keep showing "我们检测到您此次登录异常，请您进行安全验证" dialog even though already verified via sms. This add-on didn't unlock read notification and 赞同，but still at least no more error dialog each time expand more answers or view a page.
You should press Ctrl+F5 refresh the page if it goto blank page for the first time.
