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

So recently I had reinstalled windows and reformated all my drives, I am also sure that this account is my only firefox account. But when i checked the sync data it shows only 1 sync data which is today 14/3/2025. I am also sure that I had left all my sync data as default therefore it should have automatically sync. But currently I do not have access to my bookmarks, etc

Hi, I switched to a new phone recently, and wasn't able to outright sync all of my open tabs from the old device. It was, however letting me access them from the tab menu on my new device, so it wasn't a big deal.

Now I can't see the other phone in the tab menu, just the sync from my PC. I don't have the old phone anymore, because it was a trade in for my current device.

Is there any way to get my old tabs back? The sync must have timed out, because there was no activity for a period of time. I have Firefox synced on all of my devices.

Thank you.

Hi, I'm new to asking the Firefox community a question, but I hope you can give me directions to solve my problem:

I currently have Firefox v. 78.15.0esr on an iMac (early 2008) running OS 10.9.5.

I know that version has been unsupported by Mozilla for a few years, but I still want to keep this computer alive after I install the latest Firefox version to the newer (refurbished) iMac M3 2023 which should come with OS 14 or OS 15.

I hope that downloading the latest Firefox for Mac version off your website should be pretty straightforward, but what I really need help on is how to bring my Profile residing in the Library/Caches/Firefox folder on my older iMac to become my Profile on the latest Firefox version on the newer iMac (while still keeping my older iMac).

Appreciate the help.

I sync tabs with multiple devices, but I cannot get my tabs to sync with my iPad. I have tried scanning the QR code from my desktop browser. I have tried entering the password. The process never finishes on the iPad, even after the desktop browser said the process was complete.

Hello Better Angels of the Internet;

Seeking advice regarding how to best use Firefox, I'm a novice (and old). I think I have a Mozilla account. Online security is my first priority. I have no Facebook, Instagram, TicToc or other. Email is as technical as I get. I have an Iphone. I text and Facetime. That's it! Appreciate any guidance- at your leisure.

Thanks, Gus

I've synced all my data (including add-ons, passwords, bookmarks, etc) to my firefox binded account on fedora linux then change my linux distro and re-setup firefox on Manjaro KDE, login and etc

found out that everything synced but my previous add-ons and open tabs are gone for good I've so many opened tabs are my custom add-ons settings on so many add-ons for personal preferences are gone

I've faced this many times but I thought somehow these days firefox might have fixed these issues but i'm so sad that all my important data are gone :(

I'm using firefox only just for sync+privacy for hassle free setup again and again over many devices otherwise i prefer tor for much anonymity and privacy

PLEASE, YOU GUYS CONSIDER WORKING ON SYNCHRONIZATION FEATURES SPECIFICALLY <ADD-ONS> AND <OPEN TABS>

thanks for reading and pl igonre my english errors

I installed firefox on other PC and I logged in with my account. Despite having synchronization for passwords, bookmarks, etc., I can't sync my data on my new PC. Why is that?

I'm trying to get my wife's firefox browsers synced - mainly her laptop and phone. I've got the phone signed in and working fine, but on her laptop there's no option to sign in and the sync option is missing from the settings menu?

It seems to be profile related as if I create a new blank profile the option is there - but if I copy all the data from her original profile the option goes missing again. Short of manually copying all her data over, I'm a bit stuck for what to do next - any ideas?

I've tried disabling any addons, restarting in troubleshooting mode etc. I've also looked at all the other solutions I can find from here (mostly related to group policies, there's nothing enabled on this) and everything seems as it should be.

I haven't tried reinstalling, but it seems like this is a profile issue rather than an installation issue?

It's a Win 11 laptop (upgraded from W10 if that makes a difference), FF version is 135.0 64 bit.

Thanks!

Running Win11 on desktop PC. Sync option offers QR code to scan but Firefox on android does not have sync scan option on settings. Despite instructions to contrary, that option is not listed on mobile. Yes I'm logged in and yes I have synced previous versions of firefox
