How often does Firefox Sync back-up data? I see there is no preference selection allowing you to change the pre-set frequency (whatever that interval may be).

There is no set interval for when it syncs the data. If you are only Syncing one device it will connect less often than if you have multiple devices. If using multiple devices, for most users it will sync about every hour, but if you use Firefox heavily it can connect more frequently.

It would seem the Firefox sync addon is very unfinished. Surely it would be preferable to have a user choice -- for example: 1/ Sync auto continually (according to how active the browser is), 2/ Sync only at end of session (when browser closed down), 3/Sync at open and close of browser, 4/Sync only on explicit request (ie. manually). And in each instance, to have the option of merge, upload and replace or download "Base common copy" (equivalent to erasing all your recent browsing history to perform a cleanup).

I hope the FF developers take note. Regards.

warmrain,

I doubt if the Sync developers are going stumble across your suggestions buried in a support forum thread here. You should provide that "feedback" here - http://hendrix.mozilla.org/ . Or maybe post that in the Google Group that the Weave / Sync developers used for communication and for providing support in the early stages of that project. I don't know how active that group is now, but I do know that a few of the Sync developers still monitor the postings there. http://groups.google.com/group/mozilla-labs-weave/topics

However, the sync action only triggers every 60-minute and there is no user-configurable option provided. Although one can put a Sync icon onto the toolbar for easier access, it is still far from practical needs.

To unlock this limitation, do the following:

1) Type “about:config” at the address bar

2) Search for “services.sync.syncInterval”

3) Change the value from 3600000 (milliseconds = 3600 seconds = 60 minutes) to any value (in millisecond) of your choice

4) Close and restart Firefox

The Sync action will now trigger at the interval you just set.

  • services.sync.scheduler.immediateInterval 60
  • services.sync.scheduler.singleDeviceInterval 86400

So there's a number of parameters already defined for this, and yet they're not exposed in the Sync UI. Baffling.
