See #82. Now Firefox itself don't save private tabs.
So, now all filtrations are hardcoded inside built-in sessions mechanism.

Also there is AMO policies that prohibit such things:

OK. I wish there could be an extension to not save history for certain tabs (or only save history of a page when wanted to) yet still kept in sessions, as Private Tab has been able to work previously. This function would be useful, and I would not need Private Browsing.

Yes, I understand. And that's why there was savePrivateTabsInSessions preference (for debug purposes, but not only).
But for now it's very difficult to alter built-in things (hard to do it correct and very hard to make something robust).
