Ehsan, have you previously seen reports like this? Any thoughts?

Hmm, no I'm not aware of an existing bug like this, and I couldn't reproduce in a new profile.

Mandar, do you happen to have any extensions installed?  May I ask you to please go to about:support in a new tab, and copy the information there and paste it here?

Ryan, if this is a regression it's pretty worrying.  Is it possible that we get some QE resources to test this please?

Thanks!

Moving to Paul to do some investigation, since he's done QA work on Private Browsing previously.

Couldn't reproduce on FX 47, 52.0a1 (2016-10-24) Win 7.
My guess is that you already logged in with those credentials in normal mode, so it's ok for Firefox in private browsing to show you data saved in normal mode (history, forms autocomplete, saved logins etc).
Please try on a new Firefox profile and make sure your first login is made in private browsing:
