Diễn đàn hỗ trợ Firefox

Hi Yesterday I replaced my computer. I'm trying to sync my account data, but unfortunately, nothing is syncing. I have all the data selected for syncing (bookmarks, history, etc.), and the logs in about:sync-log are empty. It looks like the data from your server has been cleared. Firefox is freshly installed. Please help.

I have a firefox account but I'm trying to move my bookmarks from one computer to the next. I created a firefox account but nothing moved. How can I get my bookmarks to another computer?

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.

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?

I have switched from chrome to firefox on my windows 11 laptop. I want to do the same on my pc but after signing into the Mozilla account, the bookmarks do not come in. History, and other things seem to work fine. I tried manually synchronizing in the settings over and over again but nothing works.

I have no idea what to do other than going back to chrome where things just worked and I didn't have to spend hours looking at forums for solutions that do not work...

here's a screenshot from the last txt file

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
