Thank you, vrapp!!! Your fix worked for me. From what I can tell, I think the history engine was the hang-up... I had 5000 entries to sync and it took quite a while, relatively, compared to a usual sync that only partially worked. (Before, I'd get bookmarks synced and other things, but got an error and the process was over quickly... this took some time to sync up the histories.)

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.

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.
*http://kb.mozillazine.org/Backing_up_and_restoring_bookmarks_-_Firefox
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.

"Sync encoutered an error while syncing: Unknown error. Sync will automatically retry this action."

Hi,
I want to switch from Chrome to Firefox but I have an issue with the Sync feature.
It always shows the following error: "Sync encoutered an error while syncing: Unknown error. Sync will automatically retry this action."
I already tried this workaround but it did not work: delete my Sync account, completely reset my Firefox profile, import my Chrome bookmarks (using an HTML file), setup a new Sync account (using the same address email then the previously deleted one).
But I still get the error message.
I've seen in other threads that it could be an issue with the history so I also tried to delete it but it did not work either.
Here is my last sync-log file: https://pastebin.mozilla.org/8219943
Thanks for your help.

I've finally found a solution to that Sync issue:
I downloaded the "Places Maintenance" add-on and run the integrity check routine and it seems to have fixed the issue.

I get the error message in Firefox 5 "Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action."

Hello Firefox support. I just started working on a 64 bit Windows 7 machine running Firefox 5 and am constantly getting the following Sync error: "Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action." I can't find an accurate solution on the web. Please help!

Exact same error message here here. Haven't checked our other systems. This one is:
* Firefox 5
* Canonical 1
* Ubuntu Linux 10.04 LTS

Firefox 4 BETA Sync Glitch: Sync encountered an error while syncing: Unknown error.

I have a screen shot but no where to send it to? The error says (and it's been repeated multiple times) Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action BUTTON: Sync Now" Clicked button multiple times over an hour... no use. :) (hope this helps)
Less a question than a feedback about the program. :)
I realize it will likely be fixed innately, but wanted it to be reported, as I wish to help out the BETA test. *loyal Test Pilot*
Thanks!

I'm running FF4.0.1 and still have this problem

Received an error message "sync encountered an error while syncing: Unknown error"

For 2 days now, I have received a message at the bottom of my browser stating "Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action." I have tried to change my sync settings but that has not worked. I would appreciate assistance with this issue. Thank you.

See this article: [[Firefox Sync is not working]]

Firefox 6 Linux - Sync encountered an error while syncing: Unknown error.

Linux (Ubuntu 11.04).
Firefox 6.
The syncing doesn't work anymore. This message is displayed at the bottom all the time:
"Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action."
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.

I keep getting "Sync encountered an error while syncing: unknown error. Sync will automatically retry this action." It keeps popping up at the bottom of my screen?

I keep getting "Sync encountered an error while syncing: unknown error. Sync will automatically retry this action." It keeps popping up at the bottom of my screen? I click "Sync Now" but a few seconds later it pops up again

"Sync encountered an error while syncing: Unknown error. SYnc will automatiall retry this action" - this error message keeps popping up

"Sync encountered''' an error while syncing: Unknown error. Sync will automatically retry this action" - this error message keeps popping up whenever I am on my email accounts. I hit the "Sync Now" icon, but it comes back after a while.

Note: I just tried deleting and re-creating my Sync account, reinstalling firefox, and deleting places.sqlite, with no success. And "Eooro" from the title is supposed to be "Error".

Why do I need to set up sync when I only use 1 computer. A warning showed up that says: Sync encountered an error while connecting: Unknown error. Please try again.

When I started up my computer this morning, a warning popped up saying: ! Sync encountered an error while connecting: Unknown error. Please try again.
Why do I need to set up Sync on Firefox when I only use this one computer and do not even have a cell phone?

If you do not want to use Firefox Sync any more, you can deactivate it. See instructions here: [[How do I manage my Firefox Sync account?]]

Firefox Sync Unknown Error?

Over the last few weeks of having to reinstall my OS, I've had major problems getting Firefox Sync to do its thing and synchronise a couple of years worth of data. After a few minutes, I am receiving the following error at the bottom of the page: "Sync encountered an error while synchronising: Unknown error. Sync will automatically retry this action." Which is not particularly helpful in solving the problem!
As there are no tools provided to edit data "in the cloud", there is also no way I can see to remedy this by deleting any corrupt entries. Which does not seem very promising option to me for backing up this data, some of which is very important!
Firstly, I was wondering if anyone else has been receiving this error? And secondly, I was wondering if there was any way of manually downloading the data outside of Firefox if there isn't a remedy? I would really not like to use the nuclear option and reset my account. If it is possible to get it back then I'll be able to make a safe backup and transfer my information to xmarks, which I have found is more reliable. I guess you could argue I should be making backups like these in the first place if this information is so important, but I trusted the convenience and reliability of Mozilla to handle my data, especially as before Weave came along I had never realised how valuable keeping my history between computers can be!
I am having this problem between Mac, Ubuntu and Windows versions of Firefox 4. Hope you can understand my frustrations.

This worked for me:
# In Firefox menu: go to bookmarks -> Organize bookmarks. Take there a bakup of your bookmarks. to stay on the safe side for your bookmarks.
# Go to the sync tab in your firefox preferences (edit -> preferences)
Uncheck everything except passwords and close.
# Do a sync by double clicking the sync in the status bar (bottom of firefox)
# Go back to the sync tab and reenable one by one what you need, doing a sync in between.
