firefox-user.js/scratchpad-scripts/ghacks-clear-all-up-to-57-[the-rest-inactive].js

/***

 This will reset EVERYTHING that is INACTIVE in the ghacks user.js
 release 57-alpha master, but excludes the following:
 - prefs removed since publishing on github
 - e10s section 1100
 - privacy.resistFingerprinting alternatives sections 4600 & 4700
 - deprecated section 9999

 It does not matter if you clear everything, as a restart will reapply your user.js
 Total 477 prefs from 57-alpha master: 118 inactive, 359 active
 These have been broken into two scripts for convenience
