Firefox Community Forum

I have just completed migrating my files and settings from my (not so) old windows 10 desktop computer to my windows 11 laptop. Everything seems to have gone ok, except that the Firefox bookmarks were installed and only work in the private browsing window. When I start Firefox normally, the window that opens does not have the bookmarks, and even if I enter a web address manually in this window, it will not connect. I can choose "New window" in the drop down menu and that window will have the bookmarks, but still will not connect. The only way to get the bookmarks and also be able to connect to the internet is to choose "New private window" from the drop down menu. The problem with that is that there have been occasions when I have had a need to examine my browsing history, which I can't do since Firefox doesn't save the history when in private window mode. I have tried the procedure to sync bookmarks, history, etc., but the procedure is somewhat confusing and didn't work for me. Can you simplify the procedure for me? Thanks, John Blakley

I recently refreshed Firefox. When I re-opened the program, I was logged out. I successfully logged back in, but despite saying I'm "synced", none of my settings (themes, passwords, bookmarks, etc.) are showing up, even after waiting 30 minutes. Typically sync has taken a few seconds for me. FYI, this is on my work computer and I don't have administrator access, so I would prefer a solution (if possible) that does not require an uninstallation or installation (which I cannot do without contacting an administrator). Thanks.

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.

Firefox won't sync anything since a while back, maybe since two months back, I am unable to force sync. Clearing cashe, uninstalling the app, relogging both phone and pc, neither of these syncs bookmarks across the devices. I am able to send tabs in-between the devices. Biggest issue is I can't save bookmarks on one device and expect them to be available on my other device Nokia 7.2

Hello, when I first switched from google chrome to Firefox I could not figure out how to create one browser with two profiles like I had with chrome. So I went to about:profiles and created two separate browsers not realizing you all had an option to create two profiles under one browser. I finally figured out how to have to profiles under one browser by going here https://www.tech2geek.net/how-to-use-the-new-updated-profile-manager-in-firefox-2025/#google_vignette but I can not figure out how to sync the google chrome profile that I had previously to this new profile under the same browser. How do I sync this? I hit sync and nothing changed. I am signed in and I can not figure out how to get the browser profile to sync with this new profile under one browser. I really hate how Firefox named both of these Profiles because it is extremely hard to explain this situation.

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

Hello Mozilla Support Team,

I hope you can assist me with an urgent issue. After reinstalling Windows on my PC, I lost access to my Firefox Sync data, which includes years of bookmarks, saved passwords, and browsing history.

Before formatting, I had been using Firefox Sync with my Firefox Account (sometimes signed in via Google). However, after reinstalling Windows and logging back into Firefox Sync, my data no longer appears. At one point, I saw my account showing activity from just before formatting, but now that is gone as well.

I am worried that my synced data might have been overwritten or lost during this process. Unfortunately, I do not have a local backup of my Firefox profile.

Could you please help me: - Verify if my Firefox Sync data is still stored on your servers. - Assist with recovering my synced data or advise on next steps I can take. - Provide any guidance on preventing data loss in the future.

Thank you very much for your help. I look forward to your response.

Best regards.

Dzień dobry, po zmianie urzadzenia (PC) pomimo tego ze na starym urzadzeniu zawsze byłem zalogowany do Firefoxa (synchronizacja byla automatyczna), to na nowym urządzeniu po zalogowaniu nie mam dostepu do wczesniej zapisanch zakladek oraz haseł. Prosze o pomoc, pozdrawim D.

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!

Emergency!!! I just arrived home from a trip, and on my primary pc, I had saved say 50 tabs over a number of years. I was/am interested in syncing, but I had taken no known actionable steps to do so - but when I arrived home, my primary pc did not open the previous session. I lost everything. Spent hours trying to recover the previous session. Then, I simply decided to go back seven days and restore those tabs. Eight Hundred(!!!!!) tabs were restored, from what appears to be from each of my computers. I am now deleting the 750 unnecessary & repetitive tabs (again, on my primary computer), I am now *scared to death* to boot any of my other computers and have all of my history wiped again. WTF!!!??? Thank you very much!!!

what happened:

1: my pc is broken, then I got new system and hdd. 2: I download firefox and login. 3: Press Sync now and nothing happen.

ARE YOU KIDDING ME ?

What I want:

I want my bookmark back.

I used firefox soo many years.

PLS tell me I can take it back.

I reinstalled a new win11 and downloded fresh firefox. Sync is not working and I have no previous data to resume working. All tabs and logins are not showing in new firefox. Pls fix the issue.

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 started using the new "Profiles" feature in firefox, and I created profiles one one device. However I am finding that the profiles are not syncing across my devices. Both are Windows 11 VMs, I tried doing manual syncs, singed out and back in to both devices. But the Profiles I create on each just do not seem to sync, is this the expected behavior ?
