I recently upgraded to Windows 11, and was very careful, I thought, to back up my Firefox bookmarks and the tab plugin I use to save my sessions because for whatever reason Firefox can't handle that reliably. It all worked, because I could just sync it, but now a month later I had to reinstall Windows and... I can't sync my browser.

I've tried every password I could think of. I can't recall if I wrote it down somewhere last time, or changed it since, but I'm pretty sure I'm using the right email. Right now I'm logged in with another account.

And while I see a tab session saved from last month, which is unfortunately a little out of date but better than nothing, I don't see any saved bookmarks from this year. Just one from a year ago. I have no idea what's happened exactly, but I wasn't as careful this time because the sync worked so recently.

Now I'm stuck! I have some very important bookmark folders saved, that are key to all my projects basically. I can't just start fresh. But I can't log in, can't find any password change written down in my notes, which I may just have forgotten to note down. And I can't find any contact for Firefox support.

I do value security when it comes to handling my data but there must be a way to verify who I am, and change the password using my email?

I have reset the account accidentally to recover my password all the data is lost. Could you please change the data back to my old copy on server please. I don't have a local copy of the data

My firefox just crashed and despite having sync active, saved ZERO of my dozens of tabs. in restarting, i see that despite sync still "on", it is only syncing a handful of tabs, and doesn't even update when i do so manually. am on a windows machine, but use firefox on two of these in addition to android.

will be switching to brave full time without Mozilla's help here.

thanks, z

I'm really confused about how profiles and sync work together for what I assume is a pretty common use case, especially now will all the WFH. I have two devices:

1. Personal laptop 2. Work laptop

I'd like to keep my bookmarks, history, addons etc separate, but be able to access my work environment when working from home on my personal laptop. I've read a lot about profiles and sync and multi-account container but I'm still confused as to how I achieve what I'm trying to do.

Having multiple profiles on one device is straightforward. But AFAIK if I attach two profiles to the same sync account, and try to sync both between two devices, it will only sync one of the profiles (and then merge everything if I try to sync the other). And if I have two separate sync accounts (work and personal), each with a single profile, I can't switch between them without also merging everything. How does one achieve this then?

I have a Firefox account in order to use the sync capabilities. After a sync between desktop and phone the desktop bookmarks are on my phone in an extra folder "desktop bookmarks" and vice versa the phone bookmarks are in folder "Mobile bookmarks" in my desktop Firefox. Is this normal behaviour? I would expect them in one common folder to have a seamless synching.

Best regards, Walter

Hi, some years ago sending tabs to a device worked fine, but for some time now it stopped working. Is it just me or is it a general bug? All my devices are listed in my account. It also shows that they are updated frequently. I tried sending from Windows-Firefox to Android-Firefox and back. Nothing worked. What can I do? Best regards, Eric

I have been using sync from day one: best thing ever regarding my productivity. AFAIK, credentials get encrypted before sent to the FF cloud, using information derived from my password.

Short version: what happens when I change the Firefox account password?

Long version: I'm thinking of replacing my current password, with a very long one. If I do so, will there a re-upload of my data take place? Will my credentials on the cloud become harder to crack (assume that the new password is longer and more complex).

Hello. Last night i had to reinstall windows and i lost everything. but in firefox i have loged in and synced. its also synced with my safari browser on my phone. is it possible in any way to get my bookmarks and passwords back? because everything is gone and the profile folder only shows dates after i installed firefox again!

Best Regards Kaveh

Hi,

We are currently looking for a configuration profile to disable the sync option to the users, we allow the users to sign in but not to sync the bookmarks, history, etc.

We need to deploy this profile to all the users in our environment.

I want to sync my new laptop to Firefox on my Android mobile. I am asked to:

1. Open Firefox on your mobile device. 2. Go to the menu ( on iOS or on Android) and tap Synchronise and save data 3. Tap Ready to Scan and hold your phone over this code

But this command #3 is simply is not there in the Android FF settings. I see only Synchronise Now/ Device Name / Sign Out, plus Choose What to Synchronise. Nothing else. Any ideas?

Howdy, I just need to sync Firefox on my iMac and on my MacBook Pro. But this is surprisingly difficult to do. [[this page|https://support.mozilla.org/en-US/kb/how-do-i-set-sync-my-computer]] says to "click the 'Sign In' button next to 'Sync and save data'". It shows a handy little screenshot of a Sign In button, but I cannot see said button or the Sync and save data button even though I'm signed in to Firefox. This page gives me a handy QR code to sync Firefox on my mobile device, but I want to sync Firefox on my laptop. This page [[about:preferences#searchResults]] ] says "Sorry! There are no results in Settings for 'sync'". (Why ever not?)

It seems it should be very easy to sync Firefox between two computers; indeed it should be blindingly obvious, but it's not. What am I missing here? Thanks in advance for your help.

Seems like when I tried logging in to my old account with a password reset, I somehow created a second account with the same email.

All my bookmarks and extension set ups seem to be gone.

Never had this issue, and have been using the same firefox account for like 5 years.

Yesterday on my linux computer I noticed that my container setup ise back to the default setting. Now I'm using my windows laptop, and it is als back to the defaults. I'm afraid the same thing will happen when I start using my windows desktop. Should I poll the network cable and delete my firefox sync data, so I can hopefully save my containers setup? Or is this not going to help, and I'm fucked anyway :)

As per the subject. Had to reinstall Windows 10 on my machine cos of a glitch. In the past, never had a prob with Firefox syncing to a new machine, but it didn't this time & I can't work out how to do it??

Hi, not sure what I'm doing wrong, but my logins and passwords simply will not synch between devices. I principally use a desktop Win10 machine, and an iOS version of Firefox. Have double-checked settings on both devices, tried forcing a manual sync from each to the other, all to no avail. Any ideas on what I need to do differently? TIA.

A recently added computer's Firefox is not available on the "Send Tab To Device" list.

Both computers are logged into my Firefox account and Firefox is syncing. The new computer populated with my extensions and other synced data. The new computer shows the old computer in it's Send Tab list, but the old computer does not have the new computer's Firefox name in the Send Tab list.

On both computers, I can go to the menu / Manage Account and see the list "Connected Services - Everything you are using and signed into." On both computers, I can see the other computer's Firefox name in the list, and it reports "synced a few seconds ago".

But when I use the context menu and try to send a tab under "Send Tab To Device" the new computer is not on the list.

This article does not discuss this situation. For the case of "I don’t see my device listed" it just says "Sign In", but that has already been completed and is working on both systems.
