Anyone?

Anyone, please??

I would also like to note that this happens regardless of which Firefox installation I'm using.

Hi   !

I'm going to call for help from somebody who knows about this stuff,   but we're in different time zones and it's weekend, so, it may take a little longer still ...... (sorry  !)

Hi

Thank you for your question and apologies for the delay in getting to it.

I am going to come back to you, I just need to check with the team who have helped build Sync first for some further information.

Cool, let me know about it and I'd be more than glad to provide any additional info.

When there is an 'unexpected error', logging out of the account on the computer with the issue and then sign back in often solves the problem.

You could give this a try :

- 3-bar menu => Options => Sync - Open Sync and remove account - Close and open Firefox - 3-bar menu => Options => Sync : and sign back in.

I tried that one, but it didn't work. As a matter of fact the error shows up regardless of which device I use.

Also to note is that I am able to sign in on the Addons site with my Sync account, but not on the Sync service itself and yet servers for the latter appear to be working just fine.

Make sure you allow cookies for the accounts.firefox.com domain if you aren't allowing cookies generally or use extensions that deal with cookies.

In case of issues with Sync you can try this: Disconnect from Sync and Reconnect to Sync again. You can disconnect from Sync by clicking the e-mail address in the "3-bar" Firefox menu button drop-down list or go to "Options/Preferences > Sync". Delete the signedInUser.json file in the Firefox profile folder and delete the Weave folder (Sync was formerly named Weave). Remove an existing chrome://FirefoxAccounts entry in the Firefox Password Manager. If that isn't enough then delete the prefs.js files to reset all prefs and maybe also delete the compatibility.ini file to reinitialize the profile.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

That didn't help either; even on a fresh profile I am still getting the same error message regardless of device.

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.

This may not apply to your situation, but : the Sync data format may be changed when the latest Firefox version is released. This means that any of your other devices which have not been updated will need to be updated in order to keep syncing. Note: After updating, you may need to reconnect your device.

Stab in the dark : Would you disable your add-ons (start with uBlock Origin) to see if that will make a difference  ? You only have three, so that shouldn't be that much of a hassle, and it's worth a try ......

Nope, no dice either. It seems like it has something to do with my account as regardless of which device I log in on, Sync won't let me in at all - whether it's a fresh FF install or the Android port.

And to further confirm things, I installed Firefox for the first time on an LG K10 2016 - no addons, no hacks or anything else of that sort, but I still get the same dreaded error message. :/

Another stab in the dark :

In Options => Privacy => under 'History':

You don't happen to have its set to : 'Never remember history', do you  ?

(Don't even know if that would have any effect on this, but I'm just going on a hunch ...... )

No, mmy history settings are left as it is, and as you can see above this has been reproduced on a FRESH Firefox installation.

Somebody just pointed out to me that it would be best to wait till Seburo has had a chance to contact those developers, and that this may take a while, as they live in other parts of the world ......

(I'm so sorry for having done nothing but waste your time)

As what I was thinking, since it happens regardless of platform or if it is reproduced on a clean installation or otherwise. I have a hunch my account got knackered up as prior to this I got a "your email was just returned" error upon attempting to sign in.

Bet you're right   ! i was thinking the same, and I thought that maybe deleting the account and opening a new account would do the trick ......

But let's wait and see what the experts have to say, eh  ?

Hmm, somehow I am unable to sign into Sync over the past few days or perhaps a week even, idk. At first I got an "Email just returned" error upon trying to sign in, and now I end up with an "Unexpected error". Entering about:sync-log doesn't show any entries from the present day relating to the error. And to make sure that this has nothing to do with the plugins I have on my installation, I tried signing in on a clean Firefox config to no avail.

Are you able to open this link in your browser: https://api.accounts.firefox.com/__version__

It should say something like this: ``` {

 "version": "1.92.1",
 "commit": "0f2d8080773d0dfe55c55957d95edf77f22672a3",
 "source": "https://github.com/mozilla/fxa-auth-server"

} ```
