removed, renamed or hidden in v63.0 (#523)

* 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
