Firefox Support Forum

All PC's mentioned below are on the same router and LAN, and all are using Firefox 86 x64 on Windows 10.

I have been a Firefox user for many, many years (I started using browsers in the 90's, 'nuff said). But having recently reinstalled a PC, I found myself unable to initiate sync on the new Firefox install there. I kept getting the error "NetworkError when attempting to fetch resource." in a red box when I entered my password. Perplexed, I tried creating a support ticket on another of my PC's (let's call it #2) - same error there when trying to sign in to Firefox support! I then tried to use that browser to access my account by going to Account Settings -> Manage Account. I was met with a circle animation - and a completely blank webpage.

This post is being created from my third PC, where, for some odd reason, the Manage Account function actually works, and where I was also able to sign into support. I made a change to my bookmarks on PC/Firefox #2, to see if sync was still working - and it did come through to PC #3. After that, I was finally able to start a sync on PC #1 (the newly installed one).

But I am still unable to do anything with my account on PC #2. Can't sign in to support, can't access Manage Account. And this cannot be purely about the profile or installation, as the issue was affecting PC #1 as well.

It seems like Mozilla's account management is really wobbly, and my prime suspect is the shift to "Firefox Accounts" on the support pages recently. But I'm open to being proved wrong.

Just hoping someone out there can tell me what this issue is, and how I fix it. The fact that I was unable to sign in to my Firefox Account from a completely new Firefox install makes me very uncomfortable. And my primary PC (#2) is still unable to manage that account, or sign in to the support pages.

Thanks in advance.

Hey guys,

as described in the headline my firefox browser isnt saving my firefox account after i restart my computer. I have to login manually to get acces to my personal savings etc. I checked the cookies. It allows ff to save the necessary informations. Any idea how I can fix it?

Hello,

I want to use browser synchronization. Our network is very limited. What are the domains and/or IP addresses that we need to allow? Thank you very much for your help!

I need a backup of my bookmarks, I signed out and now I have none. I have tried to backup using the recommended way, but it does not have the 50+ bookmarks. I synced before and after. Please help.

I got an email about setting up 2FA and I agree thats an improvement. But... It should work. I use Google Authenticator for many purposes and that works fine... but not with the Mozilla account...

I used the QR code and the other code to connect the account, but the code is incorrect! Please solve this before switching on 2FA!

Just before reset my hard drive for a new installation of windows, i did a manually synchro. But when I connect on firefox, all my data disapper. Like a new account. I precise I use the same e-mail, I didn't create a new account.

Cant reset my password because i get "Your Email was just Returned. Mistyped Email?" error. Any ideas where to get help with this? I found couple questions about same error and they got it solved but I dont know how. Should i send an email to some support address about this?

Hi,

I'm new to Firefox multi-account containers and I want to now put all already synced data (all my browser history, logins, bookmarks, ...) into the "personal" container. Is this possible?

If it is, there is a secondary question, is it possible to turn off synchronization of a specific container on another device?

Use case: I want to have a work container that contains all work related data and a personal container that contains all my personal data. I want to be able to access the work container on my personal laptop, but don't want to necessarily access my personal container on my work laptop. I don't really want all that stuff to be synced to my work laptop.
