User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170504105526

Steps to reproduce:

Use the private browsing mode to open this: https://www.bostonglobe.com/business/2017/05/16/get-ready-for-even-more-cars-boston-streets/hLt3FFNj0ISHNxFIAdKbEP/story.html


Actual results:

The website identifies that the tab is private, and hides the contents of the article.


Expected results:

Websites shouldn't be able to tell that users are browsing privately and/or force them to use regular tabs.

Marking as P3 [meta] tracking bug. As we discover specific vectors for sites to detect PBM we will file bugs under this one.

The original link now works for me, not sure if because of one of my extensions.

However, this is still able to detect whether the window is private: https://codepen.io/fadupla/pen/EWxKRW
