hello danielgomes, sync doesn't always happen on fixed intervals, but it depends in part on user actions and certain situations: https://wiki.mozilla.org/Firefox/Features/Instant_Sync ''edit: it appears that the normal interval with multiple devices connected to an account is 5 minutes & with only one device that changes to daily: http://mxr.mozilla.org/mozilla-release/source/mobile/android/base/sync/syncadapter/SyncAdapter.java#62''
