 did mrphs fix the whitelist problem? Can someone provide a reproducible
 test case?

 mrphs fixed the whitelist problem by restarting Tor Browser (on OS X). So
 far I'm not able to reproduce the problem I described, which makes me
 wonder if my diagnosis is incorrect. mrphs, I remember you mentioning that
 your auto-update failed in some way. Can you give more details -- what
 error did you see and how did you finally get update to work? Did you ever
 press "Restart later"?

 > While discussing this ticket with me, Kathy pointed out that changes
 made to Linux the start up script will not go in effect until that script
 is re-run, which does not happen during a "restart after update." I am not
 sure how to easily fix that, but it will prevent the
 FONTCONFIG_PATH/FONTCONFIG_FILE env variable changes made for #16672 from
 taking effect until a full "exit/start again" kind of restart is done.

 This is a good point -- if possible I would like to move that FONTCONFIG
 stuff out of environment variables and into a new Linux whitelisting
 patch, but I haven't figured out if that's possible yet.
