You might want to file an upstream bug at https://bugzilla.mozilla.org/enter_bug.cgi#h=dupes%7CFirefox to request the old behaviour back, or at least ask for a console warning when using the "-private" flag together with a URL, or when there's already a running instance.
If you do please link it here, for future reference.
