 > FWIW: the Mozilla bug is
 https://bugzilla.mozilla.org/show_bug.cgi?id=1334485. We currently
 mitigate the problem by having the intermediate cache being memory-only

 Actually, we still have the
 {{{

 }}}
 in Torbutton and it might we worth testing whether that one can go (as I
 assumed) or I misspoke. See #2739 for the `NEWNYM` part.
