The 2-year-old support page "View synced tabs from other devices" gives 2 methods for syncing all your tabs from one Windoze FF to another. Neither one does anything at all for me now. The "right-click on the device in the sidebar" sounded SO promising, but it does not cause anything at all to happen. And checking the "sync tabs" box does indeed make them all show up in the sidebar list, but does not open anything. So besides clicking on each of the hundreds of tabs listed, how can I do this, or is it just another FF functionality lost to time?

I just bought a new PC, part by part, and used my storage devices from my old PC. I formatted the windows drive and am on a fresh installation of windows 11. I tried to log in to my mozilla account, but couldn't remember my password so I used the "Forgot password" function. When I logged in, no bookmarks or history was saved. Is it possible to restore my synced data?

15/12/2025 I need to sync my firefox data from my old windows 10 laptop to my new windows 11 laptop. Do I have to download the firefox app on to my new laptop before I can sync it, and will I need a new password if I have to download the app. Im using my old password on my old laptop to write this. On the new laptop, I tried to sign into firefox on the internet but, it said my password is wrong. I'm an oldie and have no idear what to do. Iwill be very grateful for any help. Many Thanks,

                                                                                           Janet.

Everything is gone, I have had to reinstall windows 4 times in the last week with a new PC and now all my sync data is gone...Chrome remembers everything fine and Mozilla did remember everything until this install and now its not syncing anything.

If this stuff is gone so am I.

Have tried logging in with my google account, tried logging in with Moz account, tried sync button over and over tried restarting, tried uninstalling and reinstalling and manually deleting all the folders STILL NO SYNC DATA AT ALL.......

My account won't sync my old passwords and browser history. I recently reinstalled windows and when I tried to sign in to my mozilla account my data wasn't there.

Hello, my old laptop broke. I bought a new one, installed Firefox, and signed into my Firefox account. My add-ons synced, but my passwords and bookmarks are gone. I can't access the old laptop now. Is there a way to fix this without a backup file? Or are add-ons the most I can get? Both devices have been added to the devices in the Firefox account.

I had a previous account with firefox on a different computer and attempted to login on a new one, but once i logged in none of my passwords or data transferred even though it was the same account, just curious if there’s any way i can get my info onto my new computer besides using a sync key or manually importing it

I reinstalled Windows and downloaded the browser again. I logged into my account, turned on synchronization, but none of the data was synced. I am absolutely sure that synchronization was enabled on my old browser. I tried turning it off and on again, but nothing helps. Please help me get my data back!

I have finished my setup. But it keeps saying "finish setup" in the upper right corner of the browser. I have completed all the steps. I want to sync this desktop to my mozilla account. What do I do?

My syncing my desktop to my Android phone has stopped. When I try to sync, nothing happens. I'm trying to sign in and you system keeps on telling me to check my Microsoft Authenticator, but nothing happens there (on the phone) and I don't see authenticator on my desktop. I've recently changed some passwords (not Firefox) and need my phone Firefox updated. Please help.

Hello.

I have made a fresh install of Windows 11 from Windows 10, and after logging into my account everything syncs, apart from my bookmarks. As i have made a fresh install, i deleted all of my old files on the computer. Is there any way to get my bookmarks back?

installed latest FIREFOX, but cannot recover previous passwords and bookmarks Used to use 'Sync' login and password and it would auto download to the clean Firsfoc install. Now it wont ans years of passwords have vanished and I am in trouble! Please advise

I can't sync my new device without confirmation code! The email with it is not coming to this address: [email removed]@inbox.ru. I need this information from you: Full SMTP-log with ● Exact date and time of dispatch; ● Server response mxs.mail.ru; ● Correct sender and recipient addresses.

I've tryed all obvious instructions and my bookmarks toolbar will not sync

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?
