Firefox 社群討論區

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

Hello, All my fav and password have defaulted on new PC (none have synced over). I have no access to my old PC that i use firefox sync account (always save pw and urls). Faulty harddrive. On my new PC i forgot my Firefox password so did pw recovery with my MFA. All fine but none of my fav and passwords synced over (over 200 urls and 50+ passwords)

I still have my original recovery key there is no options to enter this after firefox login on my new PC.

Please help.

Hello Mozilla Support Team,

I am writing to request assistance with recovering my Firefox Sync data.

I recently reset my PC and after reinstalling Firefox and logging back into my Firefox account, my bookmarks and saved passwords are completely gone. I believe the sync may have overwritten the server-side data with an empty local profile after the reset.

Account email: [edited from public] @gmail.com Approximate date of data loss: 02 25 2026

I had been accumulating this data for approximately 1 years and it is very important to me. Could you please check if there is any backup of my sync data on your servers that could be restored?

Thank you for your help.

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.

Hello, I reinstalled win 10 on my pc and Wien i logged back into my account sync is working but no passwords, adds, bookmarks are loaded, so I have the most important question, what am I supposed to do? Thanks

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!!!

so i signed into my firefox account on a new computer and every time i hit the sync now button it brings a pop up for half a second then it disappears and no changes happen to my bookmarks or any of my other synced data.looked through the forums could not find anything that was even similar to my problem

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

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 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.

Anybody else having issues with this feature? It had been working well to send tabs from my tablet and phone to my desktop computer, which I have been doing due to the lame way that FF uses for filing bookmarks into folders on the mobile devices.

A few days ago I started seeing "unable to send" popping up after a delay, instead of "tab sent" which typically appears immediately. Sometimes, the tab is sent even though it says it wasn't and sometimes it will send it after repeated attempts, and other times it doesn't. My wireless network and ISP connection are high speed and reliable.

So far, the problem only appears when trying to send from mobile to desktop. Sending from the desktop to mobile seems to work fine. The problem started while using 147.0.4 and persists after upgrading to 148.

Cannot get FireFox browser on my Windows 11 computer to sync with my Android mobile phone or the other way around. They both can see each other but they won't sync.

Hi, I just started using Zorin 18 os and downloaded Firefox, signed in, but my bookmarks are not there. I've tried sync and that doesn't work. I've also tried the cmd prompt sudo add-apt-repository ppa:mozzillateam/ppa and it says not found.

Thank you Bonnie McKelvy

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
