Comment (by dcf):

 Experimenting with Firefox 67.0b6 shows that an additional pref is
 required to prevent an update check on the very first execution.
 attachment:0001-Bug-29611-New-way-to-disable-updates-in-meek-Moat-
 pr.2.patch sets `app.update.checkInstallTime=false`.

 `app.update.checkInstallTime` and `app.update.checkInstallTime.days`
 control update checks that are based on time passed since the build ID,
 rather than time passed since the last check. References:
