Is 'Sync Firefox data' a way to 'back-up' your browser?

(ie: Can I retrieve all my urls even if I change my iMac (etc) to a later one?) Is 'Sync Firefox data' the way to do this?

Thank you.

Recently had to get my phone repaired and did a backup beforehand (and Firefox sync was on) but when I restored my data Firefox was empty, all tabs gone. Is there any way to get them back? And if not, any way to prevent this in the future? (I did look into my history, there are no previous tabs closed)

Thank you in advance!

I use Sync on multiple computers for passwords. I have forgotten the Primary password on one of them. If I do a password reset on the one computer, does it affect the passwords stored on the Sync server, or maybe just the key4.db and logins.json folders on the computer being reset? I will not do a reset if the Sync'ed passwords could be affected, I'll just look them up on my phone. Thanks for your help!

The following content is translated using GPT machine translation. Dear Firefox team,

I encountered a problem while using the Firefox Sync service. After registering an account with one of my email addresses, I tried to log into this account on another device, but it prompted me to register again. After following the instructions and registering, I found that both Firefox accounts are associated with the same email, but they cannot be linked together. Later, I tried using a different email address, but the same issue occurred. Finally, I attempted to log in with Google, only to discover that one of the devices does not have the option to log in with Google. I suspect this might be the reason why I cannot use Sync. The Firefox version on this device is 128.02, running on Win10.

Looking forward to your response. Wishing you a pleasant day.

Dear Mozilla team, as a old fan from early days of Mozilla Firefox, Im quite dissapointed with the same issue I am facing with Firefox browser. Even I created my profile, which one you can check from which year has been created, even after I synchronised all my bookmars, passwords etc etc, still no data is restored. I formated my laptop last week and thought that this time, with syncronising I will save a lot of time buut veery dissapointed again. STILL I am not having back my 100+ login details saved on Firefox. Also tabs. Now, on my browser promts taht my account is all syncronised but still blanco browser, with not a single saved data!

I will appreciate your help to get back my data, as soon as possible.

Please help an old dummie? I have an existing FF install on a laptop. I would like to clone it (with bookmarks, settings tiles etc) onto a new PC. An article I read said open FF on the PC you want to sync. This is confusing! "Synchronising" is ambiguous, meaning 2-way. (but which way) "copy from" & "copy to" would be clear. I am worried I will synch(copy) from the new to the old....... effectively deleting/wiping out all my preferences in my original install. OR (preferably) Is there a way to just copy the whole installation from my original PC onto a USB stick & installing FF to the new PC from it? Many Thanks

so I did a factory data reset of my s22 Plus last week and I just tried to send it a tab from my Mac to my phone which doesn't work but it works the other way. The device was still signed into my account I signed it out sign it back in from the phone and every time I try to scan the QR code to connect another device from the QR code scanner in the search bar of the Firefox browser it keeps saying that I need to use like another app because it thinks it thinks I'm using the phones camera I'm not quite sure where to go from here

Hi. I want to sync with my work pc (it used to work just fine but when I synced to a newer third pc- successfully- it just stopped). When i try to sign in on the work pc it asks me for the primary password which it then FAILS to recognise to allow me to proceed! What's going on? I can't even log onto sites with saved passwords anymore. Any help appreciated.

From the subject line - I keep getting this error when trying to use Firefox Sync on my Windows 10 desktop. Sync already works on Mac and Android, and I've already verified that I'm using my primary email to login.

I’ll start off by stating that I haven’t used Firefox in few months. However today I tried using Firefox again. However I was signed out of my account. I forgot my password and made a new one. For some reason it made a new account with my original and all data, history, and passwords are gone. And there important information is some data on that really need from my other or older account that I need. And I don’t know what kind of issue this is or how to fix. Is there a way I can fix this or is it too late?

Dear Support,

I have two laptops - both identical accounts signed in and would like to sync them so that when I open Firefox on laptop 2 it will show me Firefox on laptop 1. and if laptop 2 was last used, then when open laptop 1, it shows me Firefox on laptop 2.

currently it is separate and unique instances.

how do i automate the sync?

thanks, Nicholas

For years I had my Firefox sync working fine between Win10 PC, Android and several Win10 laptops. However yesterday I installed Windows 11 on the same PC I have Windows 10 (bought new disk) just to have a fresh install. Started with installing firefox - and here when problems begin. It couldn't let me log in into Sync, I was being immediately logged out ("Account disconnected"). Somehow I managed to log in, but then all my previous data was erased (passwords, bookmarks). I thought ok, maybe later it's gonna sync. Started installing extensions, saved one password. When trying to sync tabs with Android phone it didn't work, it couldn't see any tabs (but it could share tabs between devices!). On Android I still have old passwords and bookmarks saved, same as on old Win10 (on which I got logged out). Alright - it didn't sync after restart so I removed Firefox profile on machine, started again with logging in - and it synced only ONE password that I saved previously on same Win11 machine, with extensions I freshly installed back then. So it saved to sync improper data, forgetting about old? Logged out from all of my machines in Firefox Account. Now I'm back to my original machine on Windows 10. And what? I can't log in! Same error as on Win11 after install - "Account disconnected". Checked about:sync-log and found error logs - pasted into "Troubleshooting information" of this post.

Thanks

Can not sync the bookmarks with my other PC, my account name is glkott@gmail.com and I cant sync bookmarks, favorites, with other PC

So, my old computer recently broke, but I luckily recovered all my files. I was re-downloading Firefox onto this computer, but my bookmarks and add-ons and stuff won't sync. When I searched for the solution to this, I saw someone having a similar-ish problem (https://support.mozilla.org/en-US/questions/1403774#answer-1563248), but they just said they had to wait awhile for it to sync. Now, I have a couple questions that I can't seem to get the answer to:

1. How long does it take to sync my data? How long did that person have to wait?

2. What if it never syncs and that person just got lucky? Is there some sort of alternate way to fix this faster?

I'd really appreciate help on this topic, but I'm not the best with computers. If anyone has had this problem, and figured it out, please let me know! I had a lot of bookmarks and a good amount of add-ons, I really would like to not lose those.
