Hi, <!-- For the contributor, please make sure that the thread is tagged with the "sync-failure" tag --> I understand that Firefox Sync did not connect to your mobile device on this occasion, but hopefully I should be able to help you force a Sync event to take place. Assuming you have connected the same Sync account on both your mobile and desktop copies of Firefox: In Firefox on your mobile device: # Go into the Settings menu and select ''Firefox Account''. # Tap on ''Synchronise now''. This will “force” a synchronisation of the data that is on the local device storage.
