* removed, renamed or hidden in v63.0 - 0301a - do you want to add the `[NOTE] Firefox currently checks every 12 hrs ...` to `0302a` ? The problem is it also checks for updates every time you open/reload about:preferences and in Menu>Help>About Firefox regardless of when the last check was. - 0513 - removed because follow-on-search is no longer a deletable system addon - 2703 - do we just remove `3=for n days` or add a [NOTE] that value 3 was remove in FF63 or something? - `browser.ctrlTab.recentlyUsedOrder` replaces `browser.ctrlTab.previews` but it now defaults to true. No need to list the new one under 5000 IMO * Update user.js * 1031 add more info https://bugzilla.mozilla.org/show_bug.cgi?id=1453751#c28 * 0301a: remove update-check timing info * 2703: add version deprecation for value 3  |

 ghacks user.js
The ghacks user.js is a template, which, as provided, aims to provide as much privacy and enhanced security as possible, and to reduce tracking and fingerprinting as much as possible - while minimizing any loss of functionality and breakage (but it will happen).
Everyone, experts included, should at least read the implementation wiki page, as it contains important information regarding a few ghacks user.js settings.
