Comment (by mcs):

 Replying to [comment:1 gk]:
 > While working on the design document I stumbled over #18589 again and
 after looking at it a bit at least the `NEWNYM` issue seemed trivially to
 fix. A patch is in my bug_19995_v2
 (https://gitweb.torproject.org/user/gk/torbutton.git/commit/?h=bug_19995_v2).

 This patch looks good to me.
 I don't know the answers to the questions raised on comment:2, but it does
 seem like no data should be written to SiteSecurityServiceState.txt when
 in PBM or, as suggested by bugzilla, Mozilla should treat a browser exit
 as an exit from PBM.
