Firefox Community Forum

Dear Support,

Since ages ago I've always logged into Firefox and turned on sync so whichever device I was on (or if I have formatted my PC) I would still have acces to my browser history, tabs etc. Today I've formatted my PC to switch from win 10 to win 11 and logged into firefox as usual, but after trying to Sync nothing happens. My tabs, my history, everything is empty for some reason and I cannot find my original device (the one from a few hours ago connected in win 10) in my connected devices list either.

Please help me, my whole life is in that sync :(

Best Regards, Peter

i recently had to get a new computer and had set up sync for everything however when i logged in to my new device none of my synced data was saved is there any way to get this data back i have passwords that i need that firefox forced me to use a secure generated and saved ones that i dont know

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.

so i was using my pc (and firefox) normally, when i then turned off the machine as usual.

when i turned my pc on again and opened firefox, everything was gone, i wasn't signed in and all my bookmarks and several home url's were not there, you don't need me to tell you that's not normal.

of course, i followed the most logical course of actions, i signed into my firefox account (from which i am sending this ticket), and expected all my data to magically sync, which it didn't, so i then tried to sync in manually, looking for any backup file on my pc (i couldn't find any, though i can't say i know what one looks like so...)

hopefully this can be fixed because i had auto-sync on and it would be a bummer to lose everything and slowly rebuild my browser ui from the ground up

thanks in advance, GR

Hi guys, I have been using Firefox for a long time and most of the time, I use local backup, I have saved my bookmarks on my extended hard drive but about a year ago, I found out that Firefox has a "sync" feature and it's really great. I turned on the auto-sync of bookmarks and it work but this time, I reset Windows and I was really sure that I was syncing and I checked, I opened the Profile menu, clicked "Sync Now" and waited until the rolling logo stopped. After I reinstalled windows and reinstalled firefox, logged in but I don't see the backup bookmarks like before, I tried searching but couldn't find anything, just like a new firefox and new profile. Is there a way to find the lasted bookmarks I have synced? I often have thousands of tabs open so I have used this feature before but this is the first time Firefox hasn't shown my synced bookmarks.

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.......

I recently reset my laptop, when I logged into my mozilla account on my firefox, it is hasn't synced my passwords, hisotry, bookmarks and extensions. The sync is on, I've eevn tried to manually initiate sync. Did not work.

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.

Hi! I recently lost my old laptop and I'm trying to setup my new laptop without a backup. I was logged into my mozilla account on my old browser before I lost it, but I'm not seeing any of my old tabs, bookmarks, and extensions from my old browser syncing to my new browser. Is there anything I can do to retrieve this data without having access to my old laptop? Thank to anyone who can help!

I have two computers. I logged into my account on each. However now the bookmarks are different on each computer. Completely rearranged. Also, the banking window had it's own logins and passwords, but now they are all intermixed. I just want it to work the way it did before.

Hello, I imported Bookmarks when I came to Firefox from a previous browser. The experience was terrible and challenges still linger. Firefox has come a long way, however UX still seems to be a 2nd class citizen. Bookmarks now has somewhat duplicate directories and this in turn is causing desktop/phone sync doubt and is likely missing bookmarks.

When sync breaks, it is so confusing. How can I simply have a working Bookmarks sync on desktop/phone?

Perhaps there was a challenge when I need Bookmarks to appear in the top bar when a new Tab is opened, as this was contrary to default Firefox settings.

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 was logged in to my Firefox account and was syncing with other devices, so I thought I was all set .

I formatted my C drive and reinstalled windows, but logging back into a fresh install of Firefox, none of my extensions showed up. Bookmarks and History, yes. But no extensions.

I've lost them and now I don't even remember what they were. Is there a way to check the history in my account to determine the lost extensions?

I cleaned the AppData folder to speed up the computer, then it turned out that there were Mozilla files, which threw away all my data form browser. I synced the browser data on the phone, but it didn't transfer everything (history and login data missing). What to do to have my passwords again on the computer?

I use collections with Firefox on my Android phone but cant sync them with my Windows laptop. I'm told I need to sign in to Mozilla to use collections on my laptop. Having signed into Mozilla my collections are empty meaning my Firefox collections are not syncing with either Firefox OR Mozilla, Is there a way to automatically keep them in sync?

Under sync settings I see no option to sync collections. TIA

Hello there! I have Firefox on both my (Windows) laptop and (IOS) mobile device. Several months ago (January or February, maybe?) I had to delete Firefox from my laptop and reinstall it to fix an issue. No big deal. However, whenever I check my synced tabs on my mobile device, it still shows the tabs from before I uninstalled it on my laptop as well as the taps currently opened on my laptop. It appears as if they're two separate devices. I already checked the "Connected Services" section of my account settings, and my laptop does not appear twice. I was hoping someone could point me in the right direction of how to remove the previous version of Firefox from appearing on sync on my mobile device. TIA for any help!
