Comment:

 What about `bug_21396`
 (https://gitweb.torproject.org/user/gk/torbutton.git/commit/?h=bug_21396&id=3a285294fe1db84b140db456900cdbf9a62bab0c)
 in my public Torbutton repo? I tested it with the Session Manager
 extension and flipping the pref seems to get it usable. Moreover, I tested
 on https://browserleaks.com/firefox whether flipping the pref back and
 forth in a session has the respective outcome and it does: once the pref
 is flipped to `true` values get extracted but that stops as soon as it is
 flipped back to `false` and the page is reloaded.
