nytimes detecting Private Mode
I updated to Firefox 66 on Linux yesterday. I don't know if it's the browser version, but I noticed that nytimes.com started picking up that I'm browsing the site in private mode.
Interestingly, this is something that used to happen on my Chrome book when I used private mode, but this on Firefox, this is a first for me. It may well be that nytimes changed their code to do this, but I wonder upgrade to FF 66 contributed to this.
In any case, I wonder how a site can pick up if the user is browsing in private mode.
PB if detected by the site might now let you access since they sometimes require tracking or cookies to work.

In private windows, Firefox disables saving data to disk using IndexedDB, so that is one possible characteristic sites might use.
