 {{{
 Very important side issue is that the sandboxing feature adds
 `security.sandbox.content.tempDirSuffix` pref which is a 128-bit GUID that
 allows to uniquely identify your copy of Tor Browser. It is persistent and
 leaves unique traces on every machine you use in system %TEMP% folder.
 }}}
 We should find a good way dealing with that. Maybe as a first start is to
 set the pref, so that every Windows users has the same sandbox temp dir
 name
