* RELEASES: https://github.com/arkenfox/user.js/releases
* It is best to use the arkenfox release that is optimized for and matches your Firefox version
* EVERYONE: each release
- run prefsCleaner to reset prefs made inactive, including deprecated (9999s)
ESR102
- If you are not using arkenfox v102-1... (not a definitive list)
- 2815: clearOnShutdown cookies + offlineApps should be false
- 9999: switch the appropriate deprecated section(s) back on
* Use the arkenfox release that matches your Firefox version
- DON'T wait for arkenfox to update Firefox, nothing major changes these days
* Each release
- run prefsCleaner to reset prefs made inactive, including deprecated (9999)
* ESR
- It is recommended to not use the updater, or you will get a later version which may cause issues.
So you should manually append your overrides (and keep a copy), and manually update when you
change ESR releases (arkenfox is already past that release)
- If you decide to keep updating, then the onus is on - also see section 9999
