Sorry for the delay. I see what you mean, it seems true that firefox (suddenly?) adheres to the documentation (and hasn't done so in the past?).
So in future we have to keep in mind that $firefox -private does not open a private window (anymore!) if another instance of firefox is already running, and that $firefox -private URL does not open said URL in a private window (anymore!) (which it did for a long time and until the recent past, and which seems much more sensible). Counterintuitive and probably misleading, but once learned it's possible to accept, I guess...

This does not work (in my setup) anymore. [ctrl]-[shift]-p and "new private window" from the file menu also does not always open private windows, anymore. I'm wondering if this is a security bug (it clearly is a privacy bug).. 1) $ lsb_release -rd Description: Ubuntu 19.04 Release: 19.04 2) $ apt-cache policy firefox firefox: Installed: 67.0.4+build1-0ubuntu0.19.04.1 Candidate: 67.0.4+build1-0ubuntu0.19.04.1 Version table: *** 67.0.4+build1-0ubuntu0.19.04.1 500 500 http://de.archive.ubuntu.com/ubuntu disco-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu disco-security/main amd64 Packages 100 /var/lib/dpkg/status 66.0.3+build1-0ubuntu1 500 500 http://de.archive.ubuntu.com/ubuntu disco/main amd64 Packages 3) What I expect to happen Opening a private window from the command line typing firefox -private URL should open the URL in a private window 4) What happens instead Upon the given command firefox opens the URL, but not in a private window and leaves the URL in the history of the browser.
