- 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
- 
- For instructions see:
