Sync encountered an error while syncing. Unknow error

I keep on getting the following error message: "Sync encountered an error while syncing. Unknown error. Sync will automatically retry this action." Also, at this time, my bookmarks are useless: I lost all my bookmarks and I cannot add any new ones.

Problems with bookmarks and history not working properly can be caused by a corrupted places.sqlite database file.
You can check for problems with the places.sqlite database file in the Firefox Profile Folder.

  • How to fix "Sync encountered an error while syncing:Unknown error."

    In mid July, after the firefox update, I had decided to close firefox like I usually do before I open the client for my MMORPG Aion, so I did. I end up not turning on firefox for a few days and when I did my bookmarks were gone as well as my toolbar bookmarks and my history. I start to wonder what happened and then I realised that there was a grey bar at the bottom of my browser stating, "Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action.." I had no idea why this would happen as I never had this problem before so I look at the firefox support database but since I'm quite the greenhorn when it comes to programming there was only so much I could understand. I did try looking for corrupt or locked profiles but I saw none. Now as of today it's going on 2 months since the problem began and just today I recieved the firefox 32.0 update but still have this problem so I'm at my wits end and I not sure if I'll ever get it working again. Also my sync account is the one under the new system I had updated a few days before the problem began it also seems to be working on my other devices. Im lost without my bookmarks please help.

    Hi crogs571
    The first sync report shows an error with the history:

  • Sync encountered an error while synchronising: Unknown error

    I'm using Firefox 4.0.1 on Windows 7 Home Premium 64-bit.
    I set up a sync account to transfer my history, etc. from my old desktop to my new laptop (details above). Since then, i haven't used my desktop, just the laptop.
    For about the last week or so, the following error message keeps popping up at the foot of the screen:
    "Sync encountered an error while synchronising: Unknown error. Sync will automatically retry this action." And there is a 'Sync now' button.
    I can't think of anything that I've done (installing extensions, etc.) to cause this to happen.
    Any ideas, anyone? All help appreciated.

    Go to [https://account.services.mozilla.com/ your sync account], log in, and click clear your sync data.
    Then click the Sync now button on the error message.
    The error went away for me.

  • Sync encountered an error while syncing: Unknown error.

    Bookmarks vanished on multiple computers.
    Error message on all platforms: Sync encountered an error while syncing: Unknown error.
    Android device seems unaffected. Attempts to re-sync good data from android device have no effect.
    I filed a bug report but after over 15 days it was marked as a duplicate and rolled into another bug report.
    The solutions there are way (WAY) beyond my technical level of expertise, and look to be for the unix OS.
    Something about a corrupt root.
    I've been very reluctant to clear my sync data, because the impression I get is that I'll lose all my bookmarks. The entire reason I started using Sync was to back them up!

    If you've lost bookmarks then you should make a backup copy of the JSON backups in the bookmarkbackups folder.

  • Firefox sync encountered an error while syncing

    For the past week or so I've been getting an error bar at the bottom of Firefox stating "Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action." If I click the Server Status button it says the server is working fine. I've tried resetting Firefox, no good. I've also tried removing this machine from my sync account, deleting places.sqlite and readding it to sync, also no good. Log is below:

  • Sync encountered an error while syncing only on my windows desktop not my Mac laptop

    I have a Windows 7 Ultimate desktop and a MacBook Pro (mid-2010) running OS X Lion (10.7). Firefox Sync works properly on my MacBook Pro, but I have been getting error messages on my Windows 7 Ultimate desktop that say: "Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action." Both computers have the latest version of Firefox installed (5.0.1). I have tried removing the add-on, and deactivating and reactivating the device, all on both machines. All to no avail. The only thing I can think of that I haven't yet tried is to setup a whole new Sync account, but I do not think I should have to go to that extreme. Any help is appreciated.

    If you have tried everything, you should, first open a bug with the log of your server error (so the team can fix it) and then replace the info in the server. It's probably corrupted:

  • Sync encountered an error while syncing, after 6.0.1 uptade

    Syncing was working fine, but after the 6.0.1 update on one computer, I started getting a:
    Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action.
    If I click on the Sync now button, same error. I check my sync key and it's correct.

    The problem persists even after the 6.0.2 update. At one point in time on Saturday it did sync, but it still went back to not synching.

  • How do I supress the "sync encountered an error while syncing" bar? I get it every time I connect to a work VPN that is isolated from the internet.

    Background: For work I routinely need to connect to a secure VPN that is completely isolated from the internet. When using it, I can only connect to the servers that reside within the network and the VPN software (Cisco AnyConnect + NAC Agent) seems to automatically redirect all http requests to external sites to a catch-all 'sorry you can't do that' page.
    So while connected to the VPN, Firefox Sync doesn't work and nor do I expect it to. However, my issue is that every time I connect to the VPN, Firefox silently pops up a "sync encountered an error while syncing" error message bar at the bottom of the browser, which I have to manually close. This obviously isn't the end of the world, but having to do it all the time gets annoying so I was wondering if there was a way of suppressing that particular error message or maybe getting Sync to handle the secure VPN more gracefully.

    I don't know about blocking that message, but my suggestion is to turn Sync autoconnect off, and use Sync manually.
    Type '''about:config''' in the URL bar and hit Enter. <br />
    Then type '''''autoconnect''''' in the Search bar at the top. <br />
    '''services.sync.autoconnect''' = double-click that pref to toggle it to '''false'''.
    Then to trigger a Sync manually, hit '''Sync Now''' in the Firefox menu ''(or the File menu)''.

    Retrying doesn't help.

    I had some luck doing the following - Go to https://account.services.mozilla.com/ and login using your sync info. Find the link to Clear Cache data and clear your sync cache (first time failed, then worked). Then do a manual sync to get back in sync. Seems to have cleared up my issue for the time being.
