I reinstalled Windows. Installed The last version of Firefox and logged into my account. But there weren't any of my previous settings (extensions, bookmarks, history etc.). What happened with them?

Hi,

TLDR I changed the main drive, a full clean installiation. And when I sign in in the browser it doesnt sync anything. Back when I had to change the former main drive the sync function worked perfectly. So I dont know why is just not works anymore.

Thanks.

I rarely used the Mozilla.org site. Use Firefox for about the last 20yrs, love you guys. Logged onto my Win10 laptop, 22Aug2025, about 7pm GMT+1, clicked on Firefox icon, got a little update window, it flashed, disappeared, did not seem to fully update, the screen came on for about 5sec, a flash. Then error messages each time I tried to go onto Firefox. First time this ever happened. When I reinstall I had to spend hours trying to get SYNC to retrieve my passwords, and bookmarks. Also a first, never had this problem previously. Now my history is gone as well as all the sites saved to my Firefox Home Page. What is going on? Also, these messages, I cannot find them in my ACCT. They just do not show up. If anyone answered me, I cannot find the replies. Were you hacked?

I think I did everything on the old computer, and created a recovery key. on the new computer I signed in but, the only email confirmation I received was for the old computer. Signing in from the new windows 11 computer led to being signed with windows 10 as shown under my account.

I use firefox on 3 devices, ios, windows, and mac. I want extensions to sync across windows and mac (I know ios doesn't do that). When I first got firefox on my mac, all my windows addons synced over when I signed in but now addons that I add on my windows does not go over to my mac no matter what. I already turned addon sync on and off several times on both devices and manually hit sync multiple times on both devices as well. help?

Firefox crashes. Blue dots moving next to too tabs. Problem began this morning upon opening Firefox and dialogs box asked if wanted to sync bookmarks with another device with Firefox.

I have multiple devices all using Firefox with the same account. On one of the devices I swapped the motherboard and since all payment methods in firefox disappeared. Syncing is active across all devices. On all other devices the payment methods are still available.

On the device with the new motherboard, I tried to disable payment methods sync and re-enable it but the payment methods list is still empty. How can I restore all the payment methods on this device? Why they are not syncing?

Thanks

non my my bookmarks and passwords are on my firefox and i reformatted my pc, i have never had a issue like this ever, and yes im signed into the same email i have always used and didnt do anything different

after reinstalling the OS, Firefox stopped synchronizing most of the data. Bookmarks were not transferred, and passwords and extensions were transferred less than half

As in subject ... None of my bookmarks (for instance) in my previous browser on an other computer will show up. I have tried to manually sync but nothing happens ...

Best, Johan

I logged out of my Firefox account, then reformatted my PC.

After reinstalling Windows 11, I installed Firefox on the PC computer.

When I signed in to Firefox, I expected to see my saved tabs just like I had seen them before. There is no sign of any of my previous tabs.

All my previous Shortcuts and Bookmarks are all fine.

How do I restore the previous tabs?

Hi, I created mozilla account and turned on synchronization to save my passwords, history, etc. After I done it, I formatted my pc. Now I've just downloaded mozilla and log in to my account to see that NONE of my data were saved... How is it even possible? I turned synchronization on and then selected which data I want to save. Will you be able to help my with that?

Hi. I am trying to migrate Firefox from my wife's laptop to her new one, using sync. I've followed the instructions, set up sync on the old one, then set up sync on the new one with the same account. Nothing changes! Where am I going wrong? Or will I have to do a manual transfer instead?
