Firefox Community Forum

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

Hi,

I use Firefox app in macos, android and ipados. The bookmarks across them are not synching automatically. I need to press sync manuelly to do. All apps are updated, all settings look fine. Please help me synch bookmarks across platforms. Thanks a lot.

I use an iMac (2019) and MacBook (2015) but my tabs aren't syncing between the two.

I've refreshed the syncing a few times but the MacBook is still showing two lots of tabs for the iMac, and both of them are showing pages that are no longer open.

I'd really like to be able to move between the two so if anyone has any suggestions on how to get FireFox to sync, I'd be really grateful. :-)

I am positive that I've been signed into a Firefox browser account for the past several years (to Sync my favorites, etc.) However, my laptop recently crashed and, when I signed into my Firefox account on my new computer, the bookmarks that populated are YEARS old. I'm not sure how this happened. Can anyone help?

Until few days ago i could see all the opened tabs of my first phone on pc using "Tabs from other devices" option. Today i connected another phone and now i canno't see anymore tabs from my first phone. At the moment i don't have access to the first phone as i had to rapair it. Under my mozilla account i can still see my first phone connected.

Instead of syncing my current settings, sync just overwrote them with an old, outdated copy from another device, completely ruining my addons, bookmarks and various other settings. I managed to restore the bookmarks, but is there really no proper way to undo this or prevent such thing from happening in the first place? Is there no way to control if I want to sync my setting TO the server or FROM the server? How such a vital decision is even made then and why wouldn't there be a way for a user to control that? This is so disappointing :(

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.

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?

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.
