This is the same while having Sync ON or OFF - with sync ON and a brand new profile the infobar comes back. Considering the "browser.ipProtection.enabled" pref is "true" while using a VPN enrolled account on a new profile and sync ON, shouldn't this be the same for the "browser.ipProtection.bandwidthWarningDismissedThreshold"?
